Re: Reverse proxy with Url path problem

Well,

That will work if I have only one server behind squid.

The fact is I have 2 servers behind squid :
http://mywebserver/serv1 -> http://192.168.2.1:2048
http://mywebserver/serv2 -> http://192.168.2.2:4096

And those servers must be accessible only via Squid (the reverse proxy
purpose...).

I tried to use rewrite_program, doing a perl script which rewrite the
URL. But like I said, the server 192.168.2.1 cannot be accessible
directly...
