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.

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.

497#
498# cache=n The maximum number of entries in the result cache. The
499# default limit is 262144 entries. Each cache entry usually
500# consumes at least 256 bytes. Squid currently does not remove

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.

677# TAG: acl
678# Defining an Access List
679#
680# Every access list definition must begin with an aclname and acltype,

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

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

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.

2639# Set to 0 if the peer does not support ICP or HTCP.
2640# See ICP and HTCP options below for additional details.
2641#
2642#
2643# ==== ICP OPTIONS ====
2644#
2645# You MUST also set icp_port and icp_access explicitly when using these options.
2646# The defaults will prevent peer traffic using ICP.
2647#
2648#
2649# no-query Disable ICP queries to this neighbor.
2650#

2654# replies will be accepted from it.
2655#

2657# CLOSEST_PARENT_MISSes and never FIRST_PARENT_MISSes.
2658#
2659# background-ping
2660# To only send ICP queries to this neighbor infrequently.
2661# This is used to keep the neighbor round trip time updated
2662# and is usually used in conjunction with weighted-round-robin.
2663#
2664#
2665# ==== HTCP OPTIONS ====
2666#
2667# You MUST also set htcp_port and htcp_access explicitly when using these options.
2668# The defaults will prevent peer traffic using HTCP.
2669#
2670#
2671# htcp Send HTCP, instead of ICP, queries to the neighbor.
2672# You probably also want to set the "icp-port" to 4827
2673# instead of 3130. This directive accepts a comma separated
2674# list of options described below.
2675#
2676# htcp=oldsquid Send HTCP to old Squid versions (2.5 or earlier).
2677#
2678# htcp=no-clr Send HTCP to the neighbor but without
2679# sending any CLR requests. This cannot be used with
2680# only-clr.
2681#
2682# htcp=only-clr Send HTCP to the neighbor but ONLY CLR requests.
2683# This cannot be used with no-clr.
2684#
2685# htcp=no-purge-clr
2686# Send HTCP to the neighbor including CLRs but only when
2687# they do not result from PURGE requests.

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.

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#

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.

3107# TAG: neighbor_type_domain
3108# Modify the cache_peer neighbor type when passing requests

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

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

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

3210# multiple workers, cache_mem is positive, and Squid environment
3211# supports required IPC primitives (e.g., POSIX shared memory segments
3212# and GCC-style atomic operations).
3213#
3214# To avoid blocking locks, shared memory uses opportunistic algorithms

3256#
3257# The heap GDSF policy optimizes object hit rate by keeping smaller

3259# hit. It achieves a lower byte hit rate than LFUDA though since
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.
3266#
3267# Both policies utilize a dynamic aging mechanism that prevents

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

3321#
3322# In SMP configurations, cache_dir must not precede the workers option

3334#
3335# 'Mbytes' is the amount of disk space (MB) to use under this

3340#
3341# 'L1' is the number of first-level subdirectories which

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

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.
3458#

3462
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
3517# cache_dir rock /ssd3 ... max-size=99999
3518#Default:
3519# store_dir_select_algorithm least-load
3520
3521# TAG: max_open_disk_fds
3522# To avoid having disk as the I/O bottleneck Squid can optionally
3523# bypass the on-disk cache if more than this amount of disk file
3524# descriptors are open.
3525#
3526# A value of 0 indicates no limit.
3527#Default:
3528# no limit

3530# TAG: cache_swap_low (percent, 0-100)
3531# The low-water mark for AUFS/UFS/diskd cache object eviction by
3532# the cache_replacement_policy algorithm.

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).

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

4137#
4138# Note, the 'squid -k rotate' command normally sends a USR1

6646#
6647# The acl is typically the last acl on the http_access deny line which
6648# denied access. The exceptions to this rule are:
6649# - When Squid needs to request authentication credentials. It's then
6650# the first authentication related acl encountered
6651# - When none of the http_access lines matches. It's then the last
6652# acl processed on the last http_access line.

6700# TAG: nonhierarchical_direct
6701# By default, Squid will send any non-hierarchical requests
6702# (not cacheable request type) direct to origin servers.
6703#
6704# When this is set to "off", Squid will prefer to send these
6705# requests to parents.
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:
6715# nonhierarchical_direct on
6716
6717# TAG: prefer_direct
6718# Normally Squid tries to use parents for most requests. If you for some
6719# reason like it to first try going direct and only use a parent if
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
6727# the never_direct directive. prefer_direct only modifies how Squid
6728# acts on cacheable requests.
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
6751# from the server to create a new cache entry with.
6752#Default:
6753# cache_miss_revalidate on
6754
6755# TAG: always_direct
6756# Usage: always_direct allow|deny [!]aclname ...
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.
6791#

6799#
6800# never_direct is the opposite of always_direct. Please read
6801# the description for always_direct if you have not already.
6802#
6803# With 'never_direct' you can use ACL elements to specify
6804# requests which should NEVER be forwarded directly to origin
6805# servers. For example, to force the use of a proxy for all
6806# requests, except those in your local domain use something like:
6807#
6808# acl local-servers dstdomain .foo.net
6809# never_direct deny local-servers
6810# never_direct allow all
6811#
6812# or if Squid is inside a firewall and there are local intranet
6813# servers inside the firewall use something like:
6814#
6815# acl local-intranet dstdomain .foo.net
6816# acl local-external dstdomain external.foo.net
6817# always_direct deny local-external

7506# Maximum number of bytes packet size to advertise via EDNS.
7507# Set to "none" to disable EDNS large packet support.
7508#
7509# For legacy reasons DNS UDP replies will default to 512 bytes which
7510# is too small for many responses. EDNS provides a means for Squid to
7511# negotiate receiving larger responses back immediately without having
7512# to failover with repeat requests. Responses larger than this limit
7513# will retain the old behaviour of failover to TCP DNS.
7514#
7515# Squid has no real fixed limit internally, but allowing packet sizes
7516# over 1500 bytes requires network jumbogram support and is usually not
7517# necessary.

7519# WARNING: The RFC also indicates that some older resolvers will reply
7520# with failure of the whole request if the extension is added. Some
7521# resolvers have already been identified which will reply with mangled
7522# EDNS response on occasion. Usually in response to many-KB jumbogram
7523# sizes being advertised by Squid.
