[Nagiosplug-devel] proxy_auth patch for check_http

Hello,
i've written a little patch (see attacted), which adds proxy_auth support for the
check_http command. The patch is basicly copied from the http_auth
code, just changed variable names and the header which is sent.

-This plugin will attempt to open an HTTP connection with the host. Successul\n\
-connects return STATE_OK, refusals and timeouts return STATE_CRITICAL, other\n\
-errors return STATE_UNKNOWN. Successful connects, but incorrect reponse\n\
-messages from the host result in STATE_WARNING return values. If you are\n\
-checking a virtual server that uses \"host headers\" you must supply the FQDN\n\
-\(fully qualified domain name) as the [host_name] argument.\n"
-
-#define SSLDESCRIPTION "\
-This plugin can also check whether an SSL enabled web server is able to\n\
-serve content (optionally within a specified time) or whether the X509 \n\
-certificate is still valid for the specified number of days.\n\n\
-CHECK CONTENT: check_http -w 5 -c 10 --ssl www.verisign.com\n\n\
-When the 'www.verisign.com' server returns its content within 5 seconds, a\n\
-STATE_OK will be returned. When the server returns its content but exceeds\n\
-the 5-second threshold, a STATE_WARNING will be returned. When an error occurs,\n\
-a STATE_CRITICAL will be returned.\n\n\
-CHECK CERTIFICATE: check_http www.verisign.com -C 14\n\n\
-When the certificate of 'www.verisign.com' is valid for more than 14 days, a\n\
-STATE_OK is returned. When the certificate is still valid, but for less than\n\
-14 days, a STATE_WARNING is returned. A STATE_CRITICAL will be returned when\n\
-the certificate is expired.\n"
