[squid-users] proxy cache with multi back end server !

Hello all,

I'm trying to follow the how to here :
http://wiki.squid-cache.org/SquidFaq/ReverseProxy
in the section :
Sending different requests to different back end web servers

And unfortunately I can see only one server.
I've succeeded to see the first one server with url on squid :
http://myserv/
but this url didn't work :
http://myserv/foo/

Any idea ??

Thanks for your help!

Here is my squid conf file :
