[squid-users] New open-source ICAP server mod for url rewriting and headers manipulation.

as i was working with ICAP i saw that GreasySpoon ICAP server consumes a
lot of memory and on load takes a lot of cpu from an unknown reasons so
i was looking for an alternative and didnt find one but i found a basic
icap server that i modified to be more modular and also to work with
instances\forks.

the main goal of this specific modification is to make it simple to use
for url_rewriting.

tests that was done until now for performance was on:
client--->squid\gw------->server
1Gbit lan speed between all
client spec - intel atom 410D 2gb ram opensuse
squid spec - intel atom 510D 2GB ram Gentoo + squid 3.1.19 + ruby 1.9.3_p125
server spec - 4GB core i3 opensuse 64 bit nginx serving simple html
"it's wokrs"

with apache benchmark tools:
ab -c 1000 -n 4000 "http://otherdomain_to_rewrite/"

served all requests and about 800+ reqs per sec.

download at: https://github.com/elico/squid-helpers/tree/master/echelon-mod

looking for testers to make sure that the server is good.

notes: the forks aren't build that good so in a case of termination by
exceptions runtime error only one fork goes down and you must kill all
the others manually to to restart the server.

logs have a huge amount of output on a production environment so it's
recommended to not use it at all if you dont need it.
