Hi, I am trying to set up a Squid reverse proxy, but it does not want to work according my expectations. I am serving two sites: - www.example1.com - www.example2.com I have 3 backend servers: - 10.0.0.1 - 10.0.0.2 - 10.0.0.3 I want Squid to send the - www.example1.com queries to server 10.0.0.1 - www.example2.com queries to server 10.0.0.2 - if the query contains an o=16188 HTTP parameter I want Squid to send it to 10.0.0.3 regardless of domain Example: - http://www.example1.com/?a=1&b=2 - goes to 10.0.0.1 - http://www.example2.com/?a=1&b=2 - goes to 10.0.0.2 - http://www.example1.com/?a=1&o=16188 - goes to 10.0.0.3 - http://www.example2.com/?a=1&o=16188 - goes to 10.0.0.3 My configuration looks like this: acl site1 dstdomain www.example1.com acl site2 dstdomain www.example2.com acl ocode_param urlpath_regex o=16188 http_access allow site1 http_access allow site2 http_port 80 accel defaultsite=www.example1.com vhost cache_peer 10.0.0.1 parent 80 0 no-query originserver name=server1 cache_peer 10.0.0.2 parent 80 0 no-query originserver name=server2 cache_peer 10.0.0.3 parent 80 0 no-query originserver name=server3 cache_peer_access server3 allow ocode_param cache_peer_access server1 allow site1 cache_peer_access server2 allow site2 cache_peer_access server1 deny all cache_peer_access server2 deny all cache_peer_access server3 deny all The problem is that the queries with o=16188 don't go to 10.0.0.3, but are routed to 10.0.0.1 or 10.0.0.2 instead (based on domain). Does it mean the cache_peer_access rules are not "first match first win" rules? Should I re-order them? How? I've tried this on Squid 2.6 on CentOS5.6 and Squid 3.1 on Fedora15, both behave the same. Please help, any suggestions appreciated. Thanks, Oskar
