Reverse proxy with URL rewriting

[Sylvain Beaux <sylvain.beaux@xxxxxxxxx>]

Hi all,

I've a squid installed and it works in reverse-proxy mode.
I would like to add two new backend servers but those ones require url
rewriting. The following schema shows how the user will request the 
servers :

client <---------------------> | squid |<---------------------> Server 1
   http://squid.ext.com/serv1  |   <>  |  http://server1.intranet.com/ 

                               |       |<---------------------> Server 2
   http://squid.ext.com/serv2  |   <>  |  http://server2.intranet.com/ 


I read in FAQ that I need to use a external script/program which modify
"on-the-fly" URLs.

But is there other possibilities to rewrite URL, I meen squid native
possibilities ?
if not, is it a feature scheduled in the road map ?

The problem is that we have to implement different scripts if we use a
linux or a NT system so we can't be agnostic from the OS.

Thanks,
