1# WELCOME TO SQUID 3.5.27
2# ----------------------------
3#
4# This is the documentation for the Squid configuration file.
5# This documentation can also be found online at:
6# http://www.squid-cache.org/Doc/config/
7#
8# You may wish to look at the Squid home page and wiki for the
9# FAQ and other documentation:
10# http://www.squid-cache.org/
11# http://wiki.squid-cache.org/SquidFaq
12# http://wiki.squid-cache.org/ConfigExamples
13#
14# This documentation shows what the defaults for various directives
15# happen to be. If you don't need to change the default, you should
16# leave the line out of your squid.conf in most cases.
17#
18# In some cases "none" refers to no default setting at all,
19# while in other cases it refers to the value of the option
20# - the comments for that keyword indicate if this is the case.
21#
22
23# Configuration options can be included using the "include" directive.
24# Include takes a list of files to include. Quoting and wildcards are
25# supported.
26#
27# For example,
28#
29# include /path/to/included/file/squid.acl.config
30#
31# Includes can be nested up to a hard-coded depth of 16 levels.
32# This arbitrary restriction is to prevent recursive include references
33# from causing Squid entering an infinite loop whilst trying to load
34# configuration files.
35#
36# Values with byte units
37#
38# Squid accepts size units on some size related directives. All
39# such directives are documented with a default value displaying
40# a unit.
41#
42# Units accepted by Squid are:
43# bytes - byte
44# KB - Kilobyte (1024 bytes)
45# MB - Megabyte
46# GB - Gigabyte
47#
48# Values with spaces, quotes, and other special characters
49#
50# Squid supports directive parameters with spaces, quotes, and other
51# special characters. Surround such parameters with "double quotes". Use
52# the configuration_includes_quoted_values directive to enable or
53# disable that support.
54#
55# Squid supports reading configuration option parameters from external
56# files using the syntax:
57# parameters("/path/filename")
58# For example:
59# acl whitelist dstdomain parameters("/etc/squid/whitelist.txt")
60#
61# Conditional configuration
62#
63# If-statements can be used to make configuration directives
64# depend on conditions:
65#
66# if <CONDITION>
67# ... regular configuration directives ...
68# [else
69# ... regular configuration directives ...]
70# endif
71#
72# The else part is optional. The keywords "if", "else", and "endif"
73# must be typed on their own lines, as if they were regular
74# configuration directives.
75#
76# NOTE: An else-if condition is not supported.
77#
78# These individual conditions types are supported:
79#
80# true
81# Always evaluates to true.
82# false
83# Always evaluates to false.
84# <integer> = <integer>
85# Equality comparison of two integer numbers.
86#
87#
88# SMP-Related Macros
89#
90# The following SMP-related preprocessor macros can be used.
91#
92# ${process_name} expands to the current Squid process "name"
93# (e.g., squid1, squid2, or cache1).
94#
95# ${process_number} expands to the current Squid process
96# identifier, which is an integer number (e.g., 1, 2, 3) unique
97# across all Squid processes of the current service instance.
98#
99# ${service_name} expands into the current Squid service instance
100# name identifier which is provided by -n on the command line.

304
305# OPTIONS FOR AUTHENTICATION
306# -----------------------------------------------------------------------------
307
308# TAG: auth_param
309# This is used to define parameters for the various authentication
310# schemes supported by Squid.
311#
312# format: auth_param scheme parameter [setting]
313#
314# The order in which authentication schemes are presented to the client is
315# dependent on the order the scheme first appears in config file. IE
316# has a bug (it's not RFC 2617 compliant) in that it will use the basic
317# scheme if basic is the first entry presented, even if more secure
318# schemes are presented. For now use the order in the recommended
319# settings section below. If other browsers have difficulties (don't
320# recognize the schemes offered even if you are using basic) either
321# put basic first, or disable the other schemes (by commenting out their
322# program entry).
323#
324# Once an authentication scheme is fully configured, it can only be
325# shutdown by shutting squid down and restarting. Changes can be made on
326# the fly and activated with a reconfigure. I.E. You can change to a
327# different helper, but not unconfigure the helper completely.
328#
329# Please note that while this directive defines how Squid processes
330# authentication it does not automatically activate authentication.
331# To use authentication you must in addition make use of ACLs based
332# on login name in http_access (proxy_auth, proxy_auth_regex or
333# external with %LOGIN used in the format tag). The browser will be
334# challenged for authentication on the first such acl encountered
335# in http_access processing and will also be re-challenged for new
336# login credentials if the request is being denied by a proxy_auth
337# type acl.
338#
339# WARNING: authentication can't be used in a transparently intercepting
340# proxy as the client then thinks it is talking to an origin server and
341# not the proxy. This is a limitation of bending the TCP/IP protocol to
342# transparently intercepting port 80, not a limitation in Squid.
343# Ports flagged 'transparent', 'intercept', or 'tproxy' have
344# authentication disabled.
345#
346# === Parameters common to all schemes. ===
347#
348# "program" cmdline
349# Specifies the command for the external authenticator.
350#
351# By default, each authentication scheme is not used unless a
352# program is specified.
353#
354# See http://wiki.squid-cache.org/Features/AddonHelpers for
355# more details on helper operations and creating your own.
356#
357# "key_extras" format
358# Specifies a string to be append to request line format for
359# the authentication helper. "Quoted" format values may contain
360# spaces and logformat %macros. In theory, any logformat %macro
361# can be used. In practice, a %macro expands as a dash (-) if
362# the helper request is sent before the required macro
363# information is available to Squid.
364#
365# By default, Squid uses request formats provided in
366# scheme-specific examples below (search for %credentials).
367#
368# The expanded key_extras value is added to the Squid credentials
369# cache and, hence, will affect authentication. It can be used to
370# autenticate different users with identical user names (e.g.,
371# when user authentication depends on http_port).
372#
373# Avoid adding frequently changing information to key_extras. For
374# example, if you add user source IP, and it changes frequently
375# in your environment, then max_user_ip ACL is going to treat
376# every user+IP combination as a unique "user", breaking the ACL
377# and wasting a lot of memory on those user records. It will also
378# force users to authenticate from scratch whenever their IP
379# changes.
380#
381# "realm" string
382# Specifies the protection scope (aka realm name) which is to be
383# reported to the client for the authentication scheme. It is
384# commonly part of the text the user will see when prompted for
385# their username and password.
386#
387# For Basic the default is "Squid proxy-caching web server".
388# For Digest there is no default, this parameter is mandatory.
389# For NTLM and Negotiate this parameter is ignored.
390#
391# "children" numberofchildren [startup=N] [idle=N] [concurrency=N]
392#
393# The maximum number of authenticator processes to spawn. If
394# you start too few Squid will have to wait for them to process
395# a backlog of credential verifications, slowing it down. When
396# password verifications are done via a (slow) network you are
397# likely to need lots of authenticator processes.
398#
399# The startup= and idle= options permit some skew in the exact
400# amount run. A minimum of startup=N will begin during startup
401# and reconfigure. Squid will start more in groups of up to
402# idle=N in an attempt to meet traffic needs and to keep idle=N
403# free above those traffic needs up to the maximum.
404#
405# The concurrency= option sets the number of concurrent requests
406# the helper can process. The default of 0 is used for helpers
407# who only supports one request at a time. Setting this to a
408# number greater than 0 changes the protocol used to include a
409# channel ID field first on the request/response line, allowing
410# multiple requests to be sent to the same helper in parallel
411# without waiting for the response.
412#
413# Concurrency must not be set unless it's known the helper
414# supports the input format with channel-ID fields.
415#
416# NOTE: NTLM and Negotiate schemes do not support concurrency
417# in the Squid code module even though some helpers can.
418#
419#
420#
421# === Example Configuration ===
422#

577# character.
578#
579# %ACL The name of the ACL being tested.
580# %DATA The ACL arguments. If not used then any arguments
581# is automatically added at the end of the line
582# sent to the helper.
583# NOTE: this will encode the arguments as one token,
584# whereas the default will pass each separately.
585#
586# %% The percent sign. Useful for helpers which need
587# an unchanging input format.
588#
589#
590# General request syntax:
591#
592# [channel-ID] FORMAT-values [acl-values ...]
593#
594#
595# FORMAT-values consists of transaction details expanded with
596# whitespace separation per the config file FORMAT specification
597# using the FORMAT macros listed above.
598#
599# acl-values consists of any string specified in the referencing
600# config 'acl ... external' line. see the "acl external" directive.
601#
602# Request values sent to the helper are URL escaped to protect
603# each value in requests against whitespaces.
604#
605# If using protocol=2.5 then the request sent to the helper is not
606# URL escaped to protect against whitespace.
607#
608# NOTE: protocol=3.0 is deprecated as no longer necessary.
609#
610# When using the concurrency= option the protocol is changed by
611# introducing a query channel tag in front of the request/response.
612# The query channel tag is a number between 0 and concurrency-1.
613# This value must be echoed back unchanged to Squid as the first part
614# of the response relating to its request.
615#
616#
617# The helper receives lines expanded per the above format specification
618# and for each input line returns 1 line starting with OK/ERR/BH result
619# code and optionally followed by additional keywords with more details.
620#
621#
622# General result syntax:
623#
624# [channel-ID] result keyword=value ...
625#
626# Result consists of one of the codes:
627#
628# OK
629# the ACL test produced a match.
630#
631# ERR
632# the ACL test does not produce a match.
633#
634# BH
635# An internal error occurred in the helper, preventing
636# a result being identified.
637#
638# The meaning of 'a match' is determined by your squid.conf
639# access control configuration. See the Squid wiki for details.
640#
641# Defined keywords:
642#
643# user= The users name (login)
644#
645# password= The users password (for login= cache_peer option)
646#
647# message= Message describing the reason for this response.
648# Available as %o in error pages.
649# Useful on (ERR and BH results).
650#
651# tag= Apply a tag to a request. Only sets a tag once,
652# does not alter existing tags.
653#
654# log= String to be logged in access.log. Available as
655# %ea in logformat specifications.
656#
657# clt_conn_tag= Associates a TAG with the client TCP connection.
658# Please see url_rewrite_program related documentation
659# for this kv-pair.
660#
661# Any keywords may be sent on any response whether OK, ERR or BH.
662#
663# All response keyword values need to be a single token with URL
664# escaping, or enclosed in double quotes (") and escaped using \ on
665# any double quotes or \ characters within the value. The wrapping
666# double quotes are removed before the value is interpreted by Squid.
667# \r and \n are also replace by CR and LF.
668#
669# Some example key values:
670#
671# user=John%20Smith

678# Defining an Access List
679#
680# Every access list definition must begin with an aclname and acltype,
681# followed by either type-specific arguments or a quoted filename that
682# they are read from.
683#
684# acl aclname acltype argument ...
685# acl aclname acltype "file" ...
686#
687# When using "file", the file should contain one item per line.
688#
689# Some acl types supports options which changes their default behaviour.
690# The available options are:
691#
692# -i,+i By default, regular expressions are CASE-SENSITIVE. To make them
693# case-insensitive, use the -i option. To return case-sensitive
694# use the +i option between patterns, or make a new ACL line
695# without -i.
696#
697# -n Disable lookups and address type conversions. If lookup or
698# conversion is required because the parameter type (IP or
699# domain name) does not match the message address type (domain
700# name or IP), then the ACL would immediately declare a mismatch
701# without any warnings or lookups.
702#
703# -- Used to stop processing all options, in the case the first acl
704# value has '-' character as first character (for example the '-'
705# is a valid domain name)
706#
707# Some acl types require suspending the current request in order
708# to access some external data source.
709# Those which do are marked with the tag [slow], those which
710# don't are marked as [fast].

1752# TAG: ftp_port
1753# Enables Native FTP proxy by specifying the socket address where Squid
1754# listens for FTP client requests. See http_port directive for various
1755# ways to specify the listening address and mode.
1756#
1757# Usage: ftp_port address [mode] [options]
1758#
1759# WARNING: This is a new, experimental, complex feature that has seen
1760# limited production exposure. Some Squid modules (e.g., caching) do not
1761# currently work with native FTP proxying, and many features have not
1762# even been tested for compatibility. Test well before deploying!
1763#
1764# Native FTP proxying differs substantially from proxying HTTP requests
1765# with ftp:// URIs because Squid works as an FTP server and receives
1766# actual FTP commands (rather than HTTP requests with FTP URLs).
1767#
1768# Native FTP commands accepted at ftp_port are internally converted or
1769# wrapped into HTTP-like messages. The same happens to Native FTP
1770# responses received from FTP origin servers. Those HTTP-like messages
1771# are shoveled through regular access control and adaptation layers
1772# between the FTP client and the FTP origin server. This allows Squid to
1773# examine, adapt, block, and log FTP exchanges. Squid reuses most HTTP
1774# mechanisms when shoveling wrapped FTP messages. For example,
1775# http_access and adaptation_access directives are used.
1776#
1777# Modes:
1778#
1779# intercept Same as http_port intercept. The FTP origin address is
1780# determined based on the intended destination of the
1781# intercepted connection.
1782#
1783# tproxy Support Linux TPROXY for spoofing outgoing
1784# connections using the client IP address.
1785# NP: disables authentication and maybe IPv6 on the port.
1786#
1787# By default (i.e., without an explicit mode option), Squid extracts the
1788# FTP origin address from the login@origin parameter of the FTP USER
1789# command. Many popular FTP clients support such native FTP proxying.
1790#
1791# Options:
1792#
1793# name=token Specifies an internal name for the port. Defaults to
1794# the port address. Usable with myportname ACL.
1795#
1796# ftp-track-dirs
1797# Enables tracking of FTP directories by injecting extra
1798# PWD commands and adjusting Request-URI (in wrapping
1799# HTTP requests) to reflect the current FTP server
1800# directory. Tracking is disabled by default.
1801#
1802# protocol=FTP Protocol to reconstruct accelerated and intercepted
1803# requests with. Defaults to FTP. No other accepted
1804# values have been tested with. An unsupported value
1805# results in a FATAL error. Accepted values are FTP,
1806# HTTP (or HTTP/1.1), and HTTPS (or HTTPS/1.1).

2686# Send HTCP to the neighbor including CLRs but only when
2687# they do not result from PURGE requests.
2688#
2689# htcp=forward-clr
2690# Forward any HTCP CLR requests this proxy receives to the peer.
2691#
2692#
2693# ==== PEER SELECTION METHODS ====
2694#
2695# The default peer selection method is ICP, with the first responding peer
2696# being used as source. These options can be used for better load balancing.
2697#
2698#
2699# default This is a parent cache which can be used as a "last-resort"
2700# if a peer cannot be located by any of the peer-selection methods.
2701# If specified more than once, only the first is used.
2702#
2703# round-robin Load-Balance parents which should be used in a round-robin
2704# fashion in the absence of any ICP queries.
2705# weight=N can be used to add bias.
2706#
2707# weighted-round-robin
2708# Load-Balance parents which should be used in a round-robin
2709# fashion with the frequency of each parent being based on the
2710# round trip time. Closer parents are used more often.
2711# Usually used for background-ping parents.
2712# weight=N can be used to add bias.
2713#
2714# carp Load-Balance parents which should be used as a CARP array.
2715# The requests will be distributed among the parents based on the
2716# CARP load balancing hash function based on their weight.
2717#
2718# userhash Load-balance parents based on the client proxy_auth or ident username.
2719#
2720# sourcehash Load-balance parents based on the client source IP.
2721#
2722# multicast-siblings
2723# To be used only for cache peers of type "multicast".
2724# ALL members of this multicast group have "sibling"
2725# relationship with it, not "parent". This is to a multicast
2726# group when the requested object would be fetched only from
2727# a "parent" cache, anyway. It's useful, e.g., when
2728# configuring a pool of redundant Squid proxies, being
2729# members of the same multicast group.
2730#
2731#
2732# ==== PEER SELECTION OPTIONS ====
2733#
2734# weight=N use to affect the selection of a peer during any weighted
2735# peer-selection mechanisms.
2736# The weight must be an integer; default is 1,
2737# larger weights are favored more.
2738# This option does not affect parent selection if a peering
2739# protocol is not in use.
2740#
2741# basetime=N Specify a base amount to be subtracted from round trip
2742# times of parents.
2743# It is subtracted before division by weight in calculating
2744# which parent to fectch from. If the rtt is less than the
2745# base time the rtt is set to a minimal value.
2746#
2747# ttl=N Specify a TTL to use when sending multicast ICP queries
2748# to this address.
2749# Only useful when sending to a multicast group.
2750# Because we don't accept ICP replies from random
2751# hosts, you must configure other group members as
2752# peers with the 'multicast-responder' option.
2753#
2754# no-delay To prevent access to this neighbor from influencing the
2755# delay pools.
2756#
2757# digest-url=URL Tell Squid to fetch the cache digest (if digests are
2758# enabled) for this host from the specified URL rather
2759# than the Squid default location.
2760#
2761#
2762# ==== CARP OPTIONS ====
2763#
2764# carp-key=key-specification
2765# use a different key than the full URL to hash against the peer.
2766# the key-specification is a comma-separated list of the keywords
2767# scheme, host, port, path, params
2768# Order is not important.
2769#
2770# ==== ACCELERATOR / REVERSE-PROXY OPTIONS ====
2771#
2772# originserver Causes this parent to be contacted as an origin server.
2773# Meant to be used in accelerator setups when the peer
2774# is a web server.
2775#
2776# forceddomain=name
2777# Set the Host header of requests forwarded to this peer.
2778# Useful in accelerator setups where the server (peer)
2779# expects a certain domain name but clients may request
2780# others. ie example.com or www.example.com
2781#
2782# no-digest Disable request of cache digests.
2783#
2784# no-netdb-exchange
2785# Disables requesting ICMP RTT database (NetDB).
2786#
2787#
2788# ==== AUTHENTICATION OPTIONS ====
2789#
2790# login=user:password
2791# If this is a personal/workgroup proxy and your parent
2792# requires proxy authentication.
2793#
2794# Note: The string can include URL escapes (i.e. %20 for
2795# spaces). This also means % must be written as %%.
2796#
2797# login=PASSTHRU
2798# Send login details received from client to this peer.
2799# Both Proxy- and WWW-Authorization headers are passed
2800# without alteration to the peer.
2801# Authentication is not required by Squid for this to work.
2802#
2803# Note: This will pass any form of authentication but
2804# only Basic auth will work through a proxy unless the
2805# connection-auth options are also used.
2806#
2807# login=PASS Send login details received from client to this peer.
2808# Authentication is not required by this option.
2809#
2810# If there are no client-provided authentication headers
2811# to pass on, but username and password are available
2812# from an external ACL user= and password= result tags
2813# they may be sent instead.
2814#
2815# Note: To combine this with proxy_auth both proxies must
2816# share the same user database as HTTP only allows for
2817# a single login (one for proxy, one for origin server).
2818# Also be warned this will expose your users proxy
2819# password to the peer. USE WITH CAUTION
2820#
2821# login=*:password
2822# Send the username to the upstream cache, but with a
2823# fixed password. This is meant to be used when the peer
2824# is in another administrative domain, but it is still
2825# needed to identify each user.
2826# The star can optionally be followed by some extra
2827# information which is added to the username. This can
2828# be used to identify this proxy to the peer, similar to
2829# the login=username:password option above.
2830#
2831# login=NEGOTIATE
2832# If this is a personal/workgroup proxy and your parent
2833# requires a secure proxy authentication.
2834# The first principal from the default keytab or defined by
2835# the environment variable KRB5_KTNAME will be used.
2836#
2837# WARNING: The connection may transmit requests from multiple
2838# clients. Negotiate often assumes end-to-end authentication
2839# and a single-client. Which is not strictly true here.
2840#
2841# login=NEGOTIATE:principal_name
2842# If this is a personal/workgroup proxy and your parent
2843# requires a secure proxy authentication.
2844# The principal principal_name from the default keytab or
2845# defined by the environment variable KRB5_KTNAME will be
2846# used.
2847#
2848# WARNING: The connection may transmit requests from multiple
2849# clients. Negotiate often assumes end-to-end authentication
2850# and a single-client. Which is not strictly true here.
2851#
2852# connection-auth=on|off
2853# Tell Squid that this peer does or not support Microsoft
2854# connection oriented authentication, and any such
2855# challenges received from there should be ignored.
2856# Default is auto to automatically determine the status

2954# If set to auto the header will only be added if the
2955# request is forwarded as a https:// URL.
2956#
2957#
2958# ==== GENERAL OPTIONS ====
2959#
2960# connect-timeout=N
2961# A peer-specific connect timeout.
2962# Also see the peer_connect_timeout directive.
2963#
2964# connect-fail-limit=N
2965# How many times connecting to a peer must fail before
2966# it is marked as down. Standby connection failures
2967# count towards this limit. Default is 10.
2968#
2969# allow-miss Disable Squid's use of only-if-cached when forwarding
2970# requests to siblings. This is primarily useful when
2971# icp_hit_stale is used by the sibling. Excessive use
2972# of this option may result in forwarding loops. One way
2973# to prevent peering loops when using this option, is to
2974# deny cache peer usage on requests from a peer:
2975# acl fromPeer ...
2976# cache_peer_access peerName deny fromPeer
2977#
2978# max-conn=N Limit the number of concurrent connections the Squid
2979# may open to this peer, including already opened idle
2980# and standby connections. There is no peer-specific
2981# connection limit by default.
2982#
2983# A peer exceeding the limit is not used for new
2984# requests unless a standby connection is available.
2985#
2986# max-conn currently works poorly with idle persistent
2987# connections: When a peer reaches its max-conn limit,
2988# and there are idle persistent connections to the peer,
2989# the peer may not be selected because the limiting code
2990# does not know whether Squid can reuse those idle
2991# connections.
2992#
2993# standby=N Maintain a pool of N "hot standby" connections to an
2994# UP peer, available for requests when no idle
2995# persistent connection is available (or safe) to use.
2996# By default and with zero N, no such pool is maintained.
2997# N must not exceed the max-conn limit (if any).
2998#
2999# At start or after reconfiguration, Squid opens new TCP
3000# standby connections until there are N connections
3001# available and then replenishes the standby pool as
3002# opened connections are used up for requests. A used
3003# connection never goes back to the standby pool, but
3004# may go to the regular idle persistent connection pool
3005# shared by all peers and origin servers.
3006#
3007# Squid never opens multiple new standby connections
3008# concurrently. This one-at-a-time approach minimizes
3009# flooding-like effect on peers. Furthermore, just a few
3010# standby connections should be sufficient in most cases
3011# to supply most new requests with a ready-to-use
3012# connection.
3013#
3014# Standby connections obey server_idle_pconn_timeout.
3015# For the feature to work as intended, the peer must be
3016# configured to accept and keep them open longer than
3017# the idle timeout at the connecting Squid, to minimize
3018# race conditions typical to idle used persistent
3019# connections. Default request_timeout and
3020# server_idle_pconn_timeout values ensure such a
3021# configuration.
3022#
3023# name=xxx Unique name for the peer.
3024# Required if you have multiple peers on the same host
3025# but different ports.
3026# This name can be used in cache_peer_access and similar
3027# directives to identify the peer.
3028# Can be used by outgoing access controls through the
3029# peername ACL type.
3030#
3031# no-tproxy Do not use the client-spoof TPROXY support when forwarding
3032# requests to this peer. Use normal address selection instead.
3033# This overrides the spoof_client_ip ACL.
3034#
3035# proxy-only objects fetched from the peer will not be stored locally.
3036#
3037#Default:
3038# none
3039
3040# TAG: cache_peer_domain
3041# Use to limit the domains for which a neighbor cache will be
3042# queried.
3043#
3044# Usage:
3045# cache_peer_domain cache-host domain [domain ...]
3046# cache_peer_domain cache-host !domain
3047#
3048# For example, specifying
3049#
3050# cache_peer_domain parent.foo.net .edu
3051#
3052# has the effect such that UDP query packets are sent to
3053# 'bigserver' only when the requested object exists on a
3054# server in the .edu domain. Prefixing the domainname
3055# with '!' means the cache will be queried for objects
3056# NOT in that domain.
3057#
3058# NOTE: * Any number of domains may be given for a cache-host,
3059# either on the same or separate lines.
3060# * When multiple domains are given for a particular
3061# cache-host, the first matched domain is applied.
3062# * Cache hosts with no domain restrictions are queried
3063# for all requests.
3064# * There are no defaults.
3065# * There is also a 'cache_peer_access' tag in the ACL
3066# section.
3067#Default:
3068# none
3069
3070# TAG: cache_peer_access
3071# Restricts usage of cache_peer proxies.
3072#
3073# Usage:
3074# cache_peer_access peer-name allow|deny [!]aclname ...
3075#
3076# For the required peer-name parameter, use either the value of the
3077# cache_peer name=value parameter or, if name=value is missing, the
3078# cache_peer hostname parameter.
3079#
3080# This directive narrows down the selection of peering candidates, but
3081# does not determine the order in which the selected candidates are
3082# contacted. That order is determined by the peer selection algorithms
3083# (see PEER SELECTION sections in the cache_peer documentation).
3084#
3085# If a deny rule matches, the corresponding peer will not be contacted
3086# for the current transaction -- Squid will not send ICP queries and
3087# will not forward HTTP requests to that peer. An allow match leaves
3088# the corresponding peer in the selection. The first match for a given
3089# peer wins for that peer.
3090#
3091# The relative order of cache_peer_access directives for the same peer
3092# matters. The relative order of any two cache_peer_access directives
3093# for different peers does not matter. To ease interpretation, it is a
3094# good idea to group cache_peer_access directives for the same peer
3095# together.
3096#
3097# A single cache_peer_access directive may be evaluated multiple times
3098# for a given transaction because individual peer selection algorithms
3099# may check it independently from each other. These redundant checks
3100# may be optimized away in future Squid versions.
3101#
3102# This clause only supports fast acl types.
3103# See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
3104#Default:
3105# No peer usage restrictions.
3106
3107# TAG: neighbor_type_domain
3108# Modify the cache_peer neighbor type when passing requests
3109# about specific domains to the peer.
3110#
3111# Usage:
3112# neighbor_type_domain neighbor parent|sibling domain domain ...
3113#
3114# For example:
3115# cache_peer foo.example.com parent 3128 3130
3116# neighbor_type_domain foo.example.com sibling .au .de
3117#
3118# The above configuration treats all requests to foo.example.com as a
3119# parent proxy unless the request is for a .au or .de ccTLD domain name.
3120#Default:
3121# The peer type from cache_peer directive is used for all requests to that peer.
3122
3123# TAG: dead_peer_timeout (seconds)
3124# This controls how long Squid waits to declare a peer cache
3125# as "dead." If there are no ICP replies received in this
3126# amount of time, Squid will declare the peer dead and not
3127# expect to receive any further ICP replies. However, it
3128# continues to send ICP queries, and will mark the peer as
3129# alive upon receipt of the first subsequent ICP reply.
3130#
3131# This timeout also affects when Squid expects to receive ICP
3132# replies from peers. If more than 'dead_peer' seconds have
3133# passed since the last ICP reply was received, Squid will not
3134# expect to receive an ICP reply on the next query. Thus, if
3135# your time between requests is greater than this timeout, you
3136# will see a lot of requests sent DIRECT to origin servers
3137# instead of to your parents.
3138#Default:
3139# dead_peer_timeout 10 seconds
3140
3141# TAG: forward_max_tries
3142# Controls how many different forward paths Squid will try
3143# before giving up. See also forward_timeout.
3144#
3145# NOTE: connect_retries (default: none) can make each of these
3146# possible forwarding paths be tried multiple times.
3147#Default:
3148# forward_max_tries 25
3149
3150# MEMORY CACHE OPTIONS
3151# -----------------------------------------------------------------------------
3152
3153# TAG: cache_mem (bytes)
3154# NOTE: THIS PARAMETER DOES NOT SPECIFY THE MAXIMUM PROCESS SIZE.
3155# IT ONLY PLACES A LIMIT ON HOW MUCH ADDITIONAL MEMORY SQUID WILL
3156# USE AS A MEMORY CACHE OF OBJECTS. SQUID USES MEMORY FOR OTHER
3157# THINGS AS WELL. SEE THE SQUID FAQ SECTION 8 FOR DETAILS.
3158#
3159# 'cache_mem' specifies the ideal amount of memory to be used
3160# for:
3161# * In-Transit objects
3162# * Hot Objects
3163# * Negative-Cached objects
3164#
3165# Data for these objects are stored in 4 KB blocks. This
3166# parameter specifies the ideal upper limit on the total size of
3167# 4 KB blocks allocated. In-Transit objects take the highest
3168# priority.
3169#
3170# In-transit objects have priority over the others. When
3171# additional space is needed for incoming data, negative-cached
3172# and hot objects will be released. In other words, the
3173# negative-cached and hot objects will fill up any unused space
3174# not needed for in-transit objects.
3175#
3176# If circumstances require, this limit will be exceeded.
3177# Specifically, if your incoming request rate requires more than
3178# 'cache_mem' of memory to hold in-transit objects, Squid will
3179# exceed this limit to satisfy the new requests. When the load
3180# decreases, blocks will be freed until the high-water mark is
3181# reached. Thereafter, blocks will be used to store hot
3182# objects.
3183#
3184# If shared memory caching is enabled, Squid does not use the shared
3185# cache space for in-transit objects, but they still consume as much
3186# local memory as they need. For more details about the shared memory
3187# cache, see memory_cache_shared.
3188#Default:
3189# cache_mem 256 MB
3190
3191# TAG: maximum_object_size_in_memory (bytes)
3192# Objects greater than this size will not be attempted to kept in
3193# the memory cache. This should be set high enough to keep objects
3194# accessed frequently in memory to improve performance whilst low
3195# enough to keep larger objects from hoarding cache_mem.
3196#Default:
3197# maximum_object_size_in_memory 512 KB
3198
3199# TAG: memory_cache_shared on|off
3200# Controls whether the memory cache is shared among SMP workers.
3201#
3202# The shared memory cache is meant to occupy cache_mem bytes and replace
3203# the non-shared memory cache, although some entities may still be
3204# cached locally by workers for now (e.g., internal and in-transit
3205# objects may be served from a local memory cache even if shared memory
3206# caching is enabled).
3207#
3208# By default, the memory cache is shared if and only if all of the
3209# following conditions are satisfied: Squid runs in SMP mode with
3210# multiple workers, cache_mem is positive, and Squid environment
3211# supports required IPC primitives (e.g., POSIX shared memory segments

3254#
3255# The LRU policies keeps recently referenced objects.
3256#
3257# The heap GDSF policy optimizes object hit rate by keeping smaller
3258# popular objects in cache so it has a better chance of getting a

3260# it evicts larger (possibly popular) objects.
3261#
3262# The heap LFUDA policy keeps popular objects in cache regardless of
3263# their size and thus optimizes byte hit rate at the expense of
3264# hit rate since one large, popular object will prevent many
3265# smaller, slightly less popular objects from being cached.

3307# cache_dir Type Directory-Name Fs-specific-data [options]
3308#
3309# You can specify multiple cache_dir lines to spread the
3310# cache among different disk partitions.
3311#
3312# Type specifies the kind of storage system to use. Only "ufs"
3313# is built by default. To enable any of the other storage systems
3314# see the --enable-storeio configure option.
3315#
3316# 'Directory' is a top-level directory where cache swap
3317# files will be stored. If you want to use an entire disk
3318# for caching, this can be the mount-point directory.
3319# The directory must exist and be writable by the Squid
3320# process. Squid will NOT create this directory for you.
3321#
3322# In SMP configurations, cache_dir must not precede the workers option
3323# and should use configuration macros or conditionals to give each
3324# worker interested in disk caching a dedicated cache directory.
3325#
3326#
3327# ==== The ufs store type ====
3328#
3329# "ufs" is the old well-known Squid storage format that has always
3330# been there.
3331#
3332# Usage:
3333# cache_dir ufs Directory-Name Mbytes L1 L2 [options]
3334#
3335# 'Mbytes' is the amount of disk space (MB) to use under this
3336# directory. The default is 100 MB. Change this to suit your
3337# configuration. Do NOT put the size of your disk drive here.
3338# Instead, if you want Squid to use the entire disk drive,
3339# subtract 20% and use that value.
3340#
3341# 'L1' is the number of first-level subdirectories which
3342# will be created under the 'Directory'. The default is 16.
3343#
3344# 'L2' is the number of second-level subdirectories which
3345# will be created under each first-level directory. The default
3346# is 256.
3347#
3348#
3349# ==== The aufs store type ====
3350#
3351# "aufs" uses the same storage format as "ufs", utilizing
3352# POSIX-threads to avoid blocking the main Squid process on
3353# disk-I/O. This was formerly known in Squid as async-io.
3354#
3355# Usage:
3356# cache_dir aufs Directory-Name Mbytes L1 L2 [options]
3357#
3358# see argument descriptions under ufs above
3359#
3360#
3361# ==== The diskd store type ====
3362#
3363# "diskd" uses the same storage format as "ufs", utilizing a
3364# separate process to avoid blocking the main Squid process on
3365# disk-I/O.
3366#
3367# Usage:
3368# cache_dir diskd Directory-Name Mbytes L1 L2 [options] [Q1=n] [Q2=n]
3369#
3370# see argument descriptions under ufs above
3371#
3372# Q1 specifies the number of unacknowledged I/O requests when Squid
3373# stops opening new files. If this many messages are in the queues,
3374# Squid won't open new files. Default is 64
3375#
3376# Q2 specifies the number of unacknowledged messages when Squid
3377# starts blocking. If this many messages are in the queues,
3378# Squid blocks until it receives some replies. Default is 72
3379#
3380# When Q1 < Q2 (the default), the cache directory is optimized
3381# for lower response time at the expense of a decrease in hit
3382# ratio. If Q1 > Q2, the cache directory is optimized for
3383# higher hit ratio at the expense of an increase in response
3384# time.
3385#
3386#
3387# ==== The rock store type ====
3388#
3389# Usage:
3390# cache_dir rock Directory-Name Mbytes [options]
3391#
3392# The Rock Store type is a database-style storage. All cached
3393# entries are stored in a "database" file, using fixed-size slots.
3394# A single entry occupies one or more slots.
3395#
3396# If possible, Squid using Rock Store creates a dedicated kid
3397# process called "disker" to avoid blocking Squid worker(s) on disk
3398# I/O. One disker kid is created for each rock cache_dir. Diskers
3399# are created only when Squid, running in daemon mode, has support
3400# for the IpcIo disk I/O module.
3401#
3402# swap-timeout=msec: Squid will not start writing a miss to or
3403# reading a hit from disk if it estimates that the swap operation
3404# will take more than the specified number of milliseconds. By
3405# default and when set to zero, disables the disk I/O time limit
3406# enforcement. Ignored when using blocking I/O module because
3407# blocking synchronous I/O does not allow Squid to estimate the
3408# expected swap wait time.
3409#
3410# max-swap-rate=swaps/sec: Artificially limits disk access using
3411# the specified I/O rate limit. Swap out requests that
3412# would cause the average I/O rate to exceed the limit are
3413# delayed. Individual swap in requests (i.e., hits or reads) are
3414# not delayed, but they do contribute to measured swap rate and
3415# since they are placed in the same FIFO queue as swap out
3416# requests, they may wait longer if max-swap-rate is smaller.
3417# This is necessary on file systems that buffer "too
3418# many" writes and then start blocking Squid and other processes
3419# while committing those writes to disk. Usually used together
3420# with swap-timeout to avoid excessive delays and queue overflows
3421# when disk demand exceeds available disk "bandwidth". By default
3422# and when set to zero, disables the disk I/O rate limit
3423# enforcement. Currently supported by IpcIo module only.
3424#
3425# slot-size=bytes: The size of a database "record" used for
3426# storing cached responses. A cached response occupies at least
3427# one slot and all database I/O is done using individual slots so
3428# increasing this parameter leads to more disk space waste while
3429# decreasing it leads to more disk I/O overheads. Should be a
3430# multiple of your operating system I/O page size. Defaults to
3431# 16KBytes. A housekeeping header is stored with each slot and
3432# smaller slot-sizes will be rejected. The header is smaller than
3433# 100 bytes.
3434#
3435#
3436# ==== COMMON OPTIONS ====
3437#
3438# no-store no new objects should be stored to this cache_dir.
3439#
3440# min-size=n the minimum object size in bytes this cache_dir
3441# will accept. It's used to restrict a cache_dir
3442# to only store large objects (e.g. AUFS) while
3443# other stores are optimized for smaller objects
3444# (e.g. Rock).
3445# Defaults to 0.
3446#
3447# max-size=n the maximum object size in bytes this cache_dir
3448# supports.
3449# The value in maximum_object_size directive sets
3450# the default unless more specific details are
3451# available (ie a small store capacity).
3452#
3453# Note: To make optimal use of the max-size limits you should order
3454# the cache_dir lines with the smallest max-size value first.
3455#
3456#Default:
3457# No disk cache. Store cache ojects only in memory.

3463# TAG: store_dir_select_algorithm
3464# How Squid selects which cache_dir to use when the response
3465# object will fit into more than one.
3466#
3467# Regardless of which algorithm is used the cache_dir min-size
3468# and max-size parameters are obeyed. As such they can affect
3469# the selection algorithm by limiting the set of considered
3470# cache_dir.
3471#
3472# Algorithms:
3473#
3474# least-load
3475#
3476# This algorithm is suited to caches with similar cache_dir
3477# sizes and disk speeds.
3478#
3479# The disk with the least I/O pending is selected.
3480# When there are multiple disks with the same I/O load ranking
3481# the cache_dir with most available capacity is selected.
3482#
3483# When a mix of cache_dir sizes are configured the faster disks
3484# have a naturally lower I/O loading and larger disks have more
3485# capacity. So space used to store objects and data throughput
3486# may be very unbalanced towards larger disks.
3487#
3488#
3489# round-robin
3490#
3491# This algorithm is suited to caches with unequal cache_dir
3492# disk sizes.
3493#
3494# Each cache_dir is selected in a rotation. The next suitable
3495# cache_dir is used.
3496#
3497# Available cache_dir capacity is only considered in relation
3498# to whether the object will fit and meets the min-size and
3499# max-size parameters.
3500#
3501# Disk I/O loading is only considered to prevent overload on slow
3502# disks. This algorithm does not spread objects by size, so any
3503# I/O loading per-disk may appear very unbalanced and volatile.
3504#
3505# If several cache_dirs use similar min-size, max-size, or other
3506# limits to to reject certain responses, then do not group such
3507# cache_dir lines together, to avoid round-robin selection bias
3508# towards the first cache_dir after the group. Instead, interleave
3509# cache_dir lines from different groups. For example:
3510#
3511# store_dir_select_algorithm round-robin
3512# cache_dir rock /hdd1 ... min-size=100000
3513# cache_dir rock /ssd1 ... max-size=99999
3514# cache_dir rock /hdd2 ... min-size=100000
3515# cache_dir rock /ssd2 ... max-size=99999
3516# cache_dir rock /hdd3 ... min-size=100000

3522# To avoid having disk as the I/O bottleneck Squid can optionally

3775# Squid handling related format codes:
3776#
3777# Ss Squid request status (TCP_MISS etc)
3778# Sh Squid hierarchy status (DEFAULT_PARENT etc)
3779#
3780# SSL-related format codes:
3781#
3782# ssl::bump_mode SslBump decision for the transaction:
3783#
3784# For CONNECT requests that initiated bumping of
3785# a connection and for any request received on
3786# an already bumped connection, Squid logs the
3787# corresponding SslBump mode ("server-first" or
3788# "client-first"). See the ssl_bump option for
3789# more information about these modes.
3790#
3791# A "none" token is logged for requests that
3792# triggered "ssl_bump" ACL evaluation matching
3793# either a "none" rule or no rules at all.
3794#
3795# In all other cases, a single dash ("-") is
3796# logged.
3797#
3798# ssl::>sni SSL client SNI sent to Squid. Available only
3799# after the peek, stare, or splice SSL bumping
3800# actions.
3801#
3802# If ICAP is enabled, the following code becomes available (as
3803# well as ICAP log codes documented with the icap_log option):
3804#
3805# icap::tt Total ICAP processing time for the HTTP
3806# transaction. The timer ticks when ICAP
3807# ACLs are checked and when ICAP
3808# transaction is in progress.
3809#
3810# If adaptation is enabled the following three codes become available:
3811#
3812# adapt::<last_h The header of the last ICAP response or
3813# meta-information from the last eCAP
3814# transaction related to the HTTP transaction.
3815# Like <h, accepts an optional header name
3816# argument.
3817#
3818# adapt::sum_trs Summed adaptation transaction response
3819# times recorded as a comma-separated list in
3820# the order of transaction start time. Each time
3821# value is recorded as an integer number,
3822# representing response time of one or more
3823# adaptation (ICAP or eCAP) transaction in
3824# milliseconds. When a failed transaction is
3825# being retried or repeated, its time is not

3827# replacement (next) transaction. See also:
3828# adapt::all_trs.
3829#
3830# adapt::all_trs All adaptation transaction response times.
3831# Same as adaptation_strs but response times of
3832# individual transactions are never added
3833# together. Instead, all transaction response
3834# times are recorded individually.
3835#
3836# You can prefix adapt::*_trs format codes with adaptation
3837# service name in curly braces to record response time(s) specific
3838# to that service. For example: %{my_service}adapt::sum_trs
3839#
3840# If SSL is enabled, the following formating codes become available:
3841#
3842# %ssl::>cert_subject The Subject field of the received client
3843# SSL certificate or a dash ('-') if Squid has
3844# received an invalid/malformed certificate or
3845# no certificate at all. Consider encoding the
3846# logged value because Subject often has spaces.
3847#
3848# %ssl::>cert_issuer The Issuer field of the received client
3849# SSL certificate or a dash ('-') if Squid has
3850# received an invalid/malformed certificate or
3851# no certificate at all. Consider encoding the
3852# logged value because Issuer often has spaces.
3853#
3854# The default formats available (which do not need re-defining) are:

3871
3872# TAG: access_log
3873# Configures whether and how Squid logs HTTP and ICP transactions.
3874# If access logging is enabled, a single line is logged for every
3875# matching HTTP or ICP request. The recommended directive formats are:
3876#
3877# access_log <module>:<place> [option ...] [acl acl ...]
3878# access_log none [acl acl ...]
3879#
3880# The following directive format is accepted but may be deprecated:
3881# access_log <module>:<place> [<logformat name> [acl acl ...]]
3882#
3883# In most cases, the first ACL name must not contain the '=' character
3884# and should not be equal to an existing logformat name. You can always
3885# start with an 'all' ACL to work around those restrictions.
3886#
3887# Will log to the specified module:place using the specified format (which
3888# must be defined in a logformat directive) those entries which match
3889# ALL the acl's specified (which must be defined in acl clauses).
3890# If no acl is specified, all requests will be logged to this destination.
3891#
3892# ===== Available options for the recommended directive format =====
3893#
3894# logformat=name Names log line format (either built-in or
3895# defined by a logformat directive). Defaults
3896# to 'squid'.
3897#
3898# buffer-size=64KB Defines approximate buffering limit for log
3899# records (see buffered_logs). Squid should not
3900# keep more than the specified size and, hence,
3901# should flush records before the buffer becomes
3902# full to avoid overflows under normal
3903# conditions (the exact flushing algorithm is
3904# module-dependent though). The on-error option
3905# controls overflow handling.
3906#
3907# on-error=die|drop Defines action on unrecoverable errors. The
3908# 'drop' action ignores (i.e., does not log)
3909# affected log records. The default 'die' action
3910# kills the affected worker. The drop action
3911# support has not been tested for modules other
3912# than tcp.
3913#
3914# ===== Modules Currently available =====
3915#
3916# none Do not log any requests matching these ACL.
3917# Do not specify Place or logformat name.
3918#
3919# stdio Write each log line to disk immediately at the completion of
3920# each request.
3921# Place: the filename and path to be written.
3922#
3923# daemon Very similar to stdio. But instead of writing to disk the log
3924# line is passed to a daemon helper for asychronous handling instead.
3925# Place: varies depending on the daemon.
3926#
3927# log_file_daemon Place: the file name and path to be written.
3928#
3929# syslog To log each request via syslog facility.
3930# Place: The syslog facility and priority level for these entries.
3931# Place Format: facility.priority
3932#
3933# where facility could be any of:
3934# authpriv, daemon, local0 ... local7 or user.
3935#
3936# And priority could be any of:
3937# err, warning, notice, info, debug.
3938#
3939# udp To send each log line as text data to a UDP receiver.
3940# Place: The destination host name or IP and port.
3941# Place Format: //host:port
3942#
3943# tcp To send each log line as text data to a TCP receiver.
3944# Lines may be accumulated before sending (see buffered_logs).
3945# Place: The destination host name or IP and port.

3953# TAG: icap_log
3954# ICAP log files record ICAP transaction summaries, one line per
3955# transaction.
3956#
3957# The icap_log option format is:
3958# icap_log <filepath> [<logformat name> [acl acl ...]]
3959# icap_log none [acl acl ...]]
3960#
3961# Please see access_log option documentation for details. The two
3962# kinds of logs share the overall configuration approach and many
3963# features.
3964#
3965# ICAP processing of a single HTTP message or transaction may
3966# require multiple ICAP transactions. In such cases, multiple
3967# ICAP transaction log lines will correspond to a single access
3968# log line.
3969#
3970# ICAP log supports many access.log logformat %codes. In ICAP context,
3971# HTTP message-related %codes are applied to the HTTP message embedded
3972# in an ICAP message. Logformat "%http::>..." codes are used for HTTP
3973# messages embedded in ICAP requests while "%http::<..." codes are used
3974# for HTTP messages embedded in ICAP responses. For example:
3975#
3976# http::>h To-be-adapted HTTP message headers sent by Squid to
3977# the ICAP service. For REQMOD transactions, these are
3978# HTTP request headers. For RESPMOD, these are HTTP
3979# response headers, but Squid currently cannot log them
3980# (i.e., %http::>h will expand to "-" for RESPMOD).
3981#
3982# http::<h Adapted HTTP message headers sent by the ICAP
3983# service to Squid (i.e., HTTP request headers in regular
3984# REQMOD; HTTP response headers in RESPMOD and during
3985# request satisfaction in REQMOD).
3986#
3987# ICAP OPTIONS transactions do not embed HTTP messages.
3988#
3989# Several logformat codes below deal with ICAP message bodies. An ICAP
3990# message body, if any, typically includes a complete HTTP message
3991# (required HTTP headers plus optional HTTP message body). When
3992# computing HTTP message body size for these logformat codes, Squid
3993# either includes or excludes chunked encoding overheads; see
3994# code-specific documentation for details.
3995#
3996# For Secure ICAP services, all size-related information is currently
3997# computed before/after TLS encryption/decryption, as if TLS was not
3998# in use at all.
3999#
4000# The following format codes are also available for ICAP logs:
4001#
4002# icap::<A ICAP server IP address. Similar to <A.
4003#
4004# icap::<service_name ICAP service name from the icap_service
4005# option in Squid configuration file.
4006#
4007# icap::ru ICAP Request-URI. Similar to ru.
4008#
4009# icap::rm ICAP request method (REQMOD, RESPMOD, or
4010# OPTIONS). Similar to existing rm.
4011#
4012# icap::>st The total size of the ICAP request sent to the ICAP
4013# server (ICAP headers + ICAP body), including chunking
4014# metadata (if any).
4015#
4016# icap::<st The total size of the ICAP response received from the
4017# ICAP server (ICAP headers + ICAP body), including
4018# chunking metadata (if any).
4019#
4020# icap::<bs The size of the ICAP response body received from the
4021# ICAP server, excluding chunking metadata (if any).
4022#
4023# icap::tr Transaction response time (in
4024# milliseconds). The timer starts when
4025# the ICAP transaction is created and
4026# stops when the transaction is completed.
4027# Similar to tr.
4028#
4029# icap::tio Transaction I/O time (in milliseconds). The
4030# timer starts when the first ICAP request
4031# byte is scheduled for sending. The timers
4032# stops when the last byte of the ICAP response
4033# is received.
4034#
4035# icap::to Transaction outcome: ICAP_ERR* for all
4036# transaction errors, ICAP_OPT for OPTION
4037# transactions, ICAP_ECHO for 204
4038# responses, ICAP_MOD for message
4039# modification, and ICAP_SAT for request

5317#
5318# Field-name is a token specifying an HTTP header name. If a
5319# standard HTTP header name is used, Squid does not check whether
5320# the new header conflicts with any existing headers or violates
5321# HTTP rules. If the request to be modified already contains a
5322# field with the same name, the old field is preserved but the
5323# header field values are not merged.

5325# Field-value is either a token or a quoted string. If quoted
5326# string format is used, then the surrounding quotes are removed
5327# while escape sequences and %macros are processed.
5328#
5329# In theory, all of the logformat codes can be used as %macros.

5789# For a class 1 delay pool, the syntax is:
5790# delay_class pool 1
5791# delay_parameters pool aggregate
5792#
5793# For a class 2 delay pool:
5794# delay_class pool 2
5795# delay_parameters pool aggregate individual
5796#
5797# For a class 3 delay pool:
5798# delay_class pool 3
5799# delay_parameters pool aggregate network individual
5800#
5801# For a class 4 delay pool:
5802# delay_class pool 4
5803# delay_parameters pool aggregate network individual user
5804#
5805# For a class 5 delay pool:
5806# delay_class pool 5
5807# delay_parameters pool tagrate
5808#
5809# The option variables are:
5810#
5811# pool a pool number - ie, a number between 1 and the
5812# number specified in delay_pools as used in
5813# delay_class lines.
5814#
5815# aggregate the speed limit parameters for the aggregate bucket
5816# (class 1, 2, 3).
5817#
5818# individual the speed limit parameters for the individual
5819# buckets (class 2, 3).
5820#
5821# network the speed limit parameters for the network buckets
5822# (class 3).
5823#
5824# user the speed limit parameters for the user buckets
5825# (class 4).
5826#
5827# tagrate the speed limit parameters for the tag buckets
5828# (class 5).
5829#
5830# A pair of delay parameters is written restore/maximum, where restore is
5831# the number of bytes (not bits - modem and network speeds are usually
5832# quoted in bits) per second placed into the bucket, and maximum is the
5833# maximum number of bytes which can be in the bucket at any time.
5834#
5835# There must be one delay_parameters line for each delay pool.
5836#
5837#
5838# For example, if delay pool number 1 is a class 2 delay pool as in the
5839# above example, and is being used to strictly limit each host to 64Kbit/sec
5840# (plus overheads), with no overall limit, the line is:
5841#
5842# delay_parameters 1 none 8000/8000
5843#
5844# Note that 8 x 8K Byte/sec -> 64K bit/sec.
5845#
5846# Note that the word 'none' is used to represent no limit.
5847#
5848#
5849# And, if delay pool number 2 is a class 3 delay pool as in the above
5850# example, and you want to limit it to a total of 256Kbit/sec (strict limit)
5851# with each 8-bit network permitted 64Kbit/sec (strict limit) and each
5852# individual host permitted 4800bit/sec with a bucket maximum size of 64Kbits
5853# to permit a decent web page to be downloaded at a decent speed
5854# (if the network is not being limited due to overuse) but slow down
5855# large downloads more significantly:
5856#
5857# delay_parameters 2 32000/32000 8000/8000 600/8000
5858#
5859# Note that 8 x 32K Byte/sec -> 256K bit/sec.
5860# 8 x 8K Byte/sec -> 64K bit/sec.
5861# 8 x 600 Byte/sec -> 4800 bit/sec.
5862#
5863#
5864# Finally, for a class 4 delay pool as in the example - each user will
5865# be limited to 128Kbits/sec no matter how many workstations they are logged into.:
5866#
5867# delay_parameters 4 32000/32000 8000/8000 600/64000 16000/16000

5876# The initial bucket percentage is used to determine how much is put
5877# in each bucket when squid starts, is reconfigured, or first notices
5878# a host accessing it (in class 2 and class 3, individual hosts and

5884# CLIENT DELAY POOL PARAMETERS
5885# -----------------------------------------------------------------------------
5886
5887# TAG: client_delay_pools
5888# This option specifies the number of client delay pools used. It must
5889# preceed other client_delay_* options.
5890#
5891# Example:
5892# client_delay_pools 2
5893#
5894# See also client_delay_parameters and client_delay_access.
5895#Default:
5896# client_delay_pools 0
5897
5898# TAG: client_delay_initial_bucket_level (percent, 0-no_limit)
5899# This option determines the initial bucket size as a percentage of
5900# max_bucket_size from client_delay_parameters. Buckets are created
5901# at the time of the "first" connection from the matching IP. Idle
5902# buckets are periodically deleted up.
5903#
5904# You can specify more than 100 percent but note that such "oversized"
5905# buckets are not refilled until their size goes down to max_bucket_size
5906# from client_delay_parameters.
5907#
5908# Example:
5909# client_delay_initial_bucket_level 50
5910#Default:
5911# client_delay_initial_bucket_level 50
5912
5913# TAG: client_delay_parameters

5915# This option configures client-side bandwidth limits using the
5916# following format:
5917#
5918# client_delay_parameters pool speed_limit max_bucket_size
5919#
5920# pool is an integer ID used for client_delay_access matching.
5921#
5922# speed_limit is bytes added to the bucket per second.
5923#
5924# max_bucket_size is the maximum size of a bucket, enforced after any
5925# speed_limit additions.
5926#
5927# Please see the delay_parameters option for more information and
5928# examples.
5929#

5944#
5945# All client_delay_access options are checked in their pool ID
5946# order, starting with pool 1. The first checked pool with allowed
5947# request is selected for the request. If no ACL matches or there
5948# are no client_delay_access options, the request bandwidth is not
5949# limited.
5950#
5951# The ACL-selected pool is then used to find the
5952# client_delay_parameters for the request. Client-side pools are
5953# not used to aggregate clients. Clients are always aggregated
5954# based on their source IP addresses (one bucket per source IP).

6649# - When Squid needs to request authentication credentials. It's then

6706#
6707# Note that in most configurations, by turning this off you will only
6708# add latency to these request without any improvement in global hit
6709# ratio.
6710#
6711# This option only sets a preference. If the parent is unavailable a
6712# direct connection to the origin server may still be attempted. To
6713# completely prevent direct connections use never_direct.
6714#Default:

6720# going direct fails set this to on.
6721#
6722# By combining nonhierarchical_direct off and prefer_direct on you
6723# can set up Squid to use a parent as a backup path if going direct
6724# fails.
6725#
6726# Note: If you want Squid to use parents for all requests see

6729#Default:
6730# prefer_direct off
6731
6732# TAG: cache_miss_revalidate on|off
6733# RFC 7232 defines a conditional request mechanism to prevent
6734# response objects being unnecessarily transferred over the network.
6735# If that mechanism is used by the client and a cache MISS occurs
6736# it can prevent new cache entries being created.
6737#
6738# This option determines whether Squid on cache MISS will pass the
6739# client revalidation request to the server or tries to fetch new
6740# content for caching. It can be useful while the cache is mostly
6741# empty to more quickly have the cache populated by generating
6742# non-conditional GETs.
6743#
6744# When set to 'on' (default), Squid will pass all client If-* headers
6745# to the server. This permits server responses without a cacheable
6746# payload to be delivered and on MISS no new cache entry is created.
6747#
6748# When set to 'off' and if the request is cacheable, Squid will
6749# remove the clients If-Modified-Since and If-None-Match headers from
6750# the request sent to the server. This requests a 200 status response

6757#
6758# Here you can use ACL elements to specify requests which should
6759# ALWAYS be forwarded by Squid to the origin servers without using
6760# any peers. For example, to always directly forward requests for
6761# local servers ignoring any parents or siblings you may have use
6762# something like:
6763#
6764# acl local-servers dstdomain my.domain.net
6765# always_direct allow local-servers
6766#
6767# To always forward FTP requests directly, use
6768#
6769# acl FTP proto FTP
6770# always_direct allow FTP
6771#
6772# NOTE: There is a similar, but opposite option named
6773# 'never_direct'. You need to be aware that "always_direct deny
6774# foo" is NOT the same thing as "never_direct allow foo". You
6775# may need to use a deny rule to exclude a more-specific case of
6776# some other rule. Example:
6777#
6778# acl local-external dstdomain external.foo.net
6779# acl local-servers dstdomain .foo.net
6780# always_direct deny local-external
6781# always_direct allow local-servers
6782#
6783# NOTE: If your goal is to make the client forward the request
6784# directly to the origin server bypassing Squid then this needs
6785# to be done in the client configuration. Squid configuration
6786# can only tell Squid how Squid should fetch the object.
6787#
6788# NOTE: This directive is not related to caching. The replies
6789# is cached as usual even if you use always_direct. To not cache
6790# the replies see the 'cache' directive.

6800# never_direct is the opposite of always_direct. Please read

6802#
6803# With 'never_direct' you can use ACL elements to specify
6804# requests which should NEVER be forwarded directly to origin

6807#
6808# acl local-servers dstdomain .foo.net
6809# never_direct deny local-servers
6810# never_direct allow all
6811#
