WELCOME TO SQUID 2.7.STABLE9-20110114
----------------------------

This is the default Squid configuration file. You may wish
to look at the Squid home page (http://www.squid-cache.org/)
for the FAQ and other documentation.

The default Squid config file shows what the defaults for
various options happen to be. If you don't need to change the
default, you shouldn't uncomment the line. Doing so may cause
run-time problems. In some cases "none" refers to no default
setting at all, while in other cases it refers to a valid
option - the comments for that keyword indicate if this is the
case.

Configuration options can be included using the "include" directive.
Include takes a list of files to include. Quoting and wildcards is
supported.

For example,

include /path/to/included/file/squid.acl.config

Includes can be nested up to a hard-coded depth of 16 levels.
This arbitrary restriction is to prevent recursive include references
from causing Squid entering an infinite loop whilst trying to load
configuration files.

OPTIONS FOR THE CACHE REGISTRATION SERVICE
-----------------------------------------------------------------------------

This section contains parameters for the (optional) cache
announcement service. This service is provided to help
cache administrators locate one another in order to join or
create cache hierarchies.

An 'announcement' message is sent (via UDP) to the registration
service by Squid. By default, the announcement message is NOT
SENT unless you enable it with 'announce_period' below.

The announcement message includes your hostname, plus the
following information from this configuration file:

http_port
icp_port
cache_mgr

All current information is processed regularly and made
available on the Web at http://www.ircache.net/Cache/Tracker/.
• announce_period
• announce_host
• announce_file
• announce_port
