Hi Folks: I'm getting puzzled with routing requests with Squid 2.7STABLE5 and how 'always_direct' and 'never_direct' works. Basically I'd like to route a requests with a specific extension to another squid instance, requests to my domain to go directly and outside requests go through my parent proxys. Following the informations in http://wiki.squid-cache.org/KnowledgeBase/HierarchyControl and in the comments of squid.conf.default I've made: # parent cache's (border caches) cache_peer proxy1.bar.com parent 3128 0 no-query no-delay round-robin no-digest name=proxy1 cache_peer proxy2.bar.com parent 3128 0 no-query no-delay round-robin no-digest name=proxy2 cache_peer proxy3.bar.com parent 3128 0 no-query no-delay round-robin no-digest name=proxy3 cache_peer proxy4.bar.com parent 3128 0 no-query no-delay round-robin no-digest name=proxy4 # other squid instance cache_peer localhost parent 3129 0 no-query no-digest name=tier2 acl bar dstdomain .bar.com acl foo dstdomain foo.bar.com acl caching_tier2 url_regex -i (\.css|\.jar|\.png|\.gif|\.jpg|\.js)$ # removing Pragma header and sending specific requests to foo header_access pragma deny caching_tier2 cache_peer_access tier2 allow caching_tier2 foo cache_peer_access tier2 deny all cache_peer_access proxy1 deny caching_tier2 foo cache_peer_access proxy2 deny caching_tier2 foo cache_peer_access proxy3 deny caching_tier2 foo cache_peer_access proxy4 deny caching_tier2 foo always_direct allow !caching_tier2 bar never_direct allow all Since 'allow' match of 'always_direct' goes directs, any request to domain 'bar.com' which doesn't matches 'caching_tier2' ACL should go direct. But what is happening is: request to http://foo.bar.com/something.jpg => routed to tier2 => OK request to http://other.bar.com/<anything> => routed to parents => NOT OK! request to http://outside.world.com/<anything> => routed to parents => OK! So...Where am I messing things up ?? :-) Thanks in advance Lucas Brasilino
