[squid-users] Cache url's with "?" question marks

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello List,

I am having problems trying to cache images*/content that comes from a
URL containing a question mark on it ('?')

Background:
I am running squid Version 2.6.STABLE17 on FreeBSD 6.2 as a reverse
proxy to accelerate content hosted in America served in Europe.

The content comes from an application that uses TOMCAT so a URL
requesting dynamic content would look similar to this:

http://domain.com/storage/storage?fileName=/.domain.com-1/usr/14348/image/thumbnail/th_8837728e67eb9cce6fa074df7619cd0d193_1_.jpg

The result of such request always results on a MISS with a log similar
to this:

TCP_MISS/200 8728 GET http://domain.com/storage/storage? -
FIRST_UP_PARENT/server_1 image/jpg

I've added this to my config: acl QUERY urlpath_regex cgi-bin as you can
see bellow but it makes no difference and I tried adding this:
acl QUERY urlpath_regex cgi-bin \? and for some reason ALL requests
result in a MISS.

Any help is greatly appreciated.

My squid config looks like this: (obviously real ip's were changed)

Also here is the result of a custom script I made to parse the
access.log that will sort and display the top 22 responses so I can
compare them with cacti, I am trying to increase the Hit ratio but so
far is extremely low.
