Squirm a url rewriter for squid

Squirm - A redirector for Squid, like mod_rewrite in Apache

see http://squirm.foote.com.au/

Squirm is a fast & configurable redirector for the Squid Internet Object Cache. It requires the GNU Regex Library (now included in the Squirm source), and of course, a working Squid. It is available free under the terms of the GNU GPL.

Squirm has the following features:

• Very, very fast
• Virtually no memory usage
• It can re-read it's config files while running by sending it a HUP signal
• Interactive test mode for checking new configs
• Full regular expression matching and replacement
• Config files for patterns and IP addresses.
• If you mess up the config file, Squirm runs in Dodo Mode so your squid keeps working :-)

I started writing it because the existing redirector scripts used too much memory and all were too slow for Squids that receive a lot of requests.

Configuring Squirm, FreeBSD example:

/usr/local/etc/squirm/squirm.conf

begin
network 0.0.0.0/0
log /var/squid/logs/squirm-private-match.log
#abort-log /var/squid/logs/squirm-private-abort.log
pattern common.patterns all
end

/usr/local/etc/squirm/common.patterns
