Thank you for the explanations. I made squid working with url rewriting. But i've got an other problem, each web server use cookie methods and I need to rewrite the Cookie path too. Is it possible ? I didn't find a solution on the FAQ. example : Web server1 >> squid : HTTP/1.1 200 OK Set-Cookie: cookie=[Token]; Path=/ squid >> user: HTTP/1.1 200 OK Set-Cookie: cookie=[Token]; Path=/serv1 Mathieu: That's my configuration: squid.conf ---------- http_port <pub-ip>:80 vhost no-connection-auth acl serv1-path urlpath_regex \/serv1(\/|$) acl serv2-path urlpath_regex \/serv2(\/|$) url_rewrite_host_header off acl all src 0.0.0.0/0.0.0.0 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 acl Safe_ports port 80 http_access deny !Safe_ports http_access deny !serv1-path !serv2-path http_reply_access allow all http_access allow manager localhost http_access deny manager always_direct allow all url_rewrite_program /etc/squid/redirector.pl url_rewrite_children 5 http_access deny all /etc/squid/redirector.pl ------------------------ #!/usr/bin/perl -p BEGIN { $|=1; } s%^http://squid.ext.com/serv1%http://server1.intranet.com%&& next; s%^http://squid.ext.com/serv2%http://server2.intranet.com%&& next; regards Sylvain
