URL + port rewriting

[vladimirg]

Hello,

I need to perform a specific task, and I thought it might be possible
to do it using Squid.
Unfortunately, I get the impression it actually not possible.
I'd be glad if someone could give me a tip or hint on a proper way to
do it:

I have a tool which is able to use a proxy server.
The tool wants to request URLs like this one:
http(s)://real.server1.com:1111/anything/goes/here

For such URLs, I'd like the proxy server to pass the request actually
to:
http(s)://test.server2.com:2222/anything/goes/here

Requests to any other URLs/ports should go intact (transparently)
trough the proxy server.

Any idea if and how it this achievable with Squid? Ot may be other
tool?
I also look at Stone repeater ( http://www.gcd.org/sengoku/stone/ ),
but I also get the impression it is not the right tool...
