I haven't tested to rewrite the querystring part of the url, but it's
available on the redirector (rewrite_program)

Here's sample input for the rewrite_program

The digit in the first position is only present when
url_rewrite_concurrency is used, see

The thread : url_rewrite_concurrency singlethreaded redirector performance?

I use :
url_rewrite_program /etc/squid/redirector.pl
url_rewrite_children 100
url_rewrite_concurrency 50
url_rewrite_host_header off

which means :

100 process spawned (busy proxy)
url_rewrite_concurrency 50, means squid can pass up to 50 URL to the
program using a counter

url_rewrite_host_header off, means that redirector rewrites the URL, but
squid keep the original URL, useful in accelerator mode (surrogate), See
the doc, to be sure.

Simple perl program :

# no buffered output, auto flush
$|=1;

while(<STDIN>)
{
   s#http://something/#http://somthingelse/#;
   print;
}

A bit fast answer, hope that helps.

Sylvain.
