Hi, I have two parent proxies configured. Parent 1 is on a faster link while Parent 2 is on a DSL. Squid 3.1.20 is the child proxy while Parent proxies are 3.1.6. I have some domains which need higher priority and should be failed-over and rest all of the traffic can be load-balanced. Here is my configuration snippet: ----------------- cache_peer 10.27.0.1 parent 8082 0 no-query no-digest connection-auth=on login=PASSTHRU round-robin proxy-only cache_peer 10.28.0.1 parent 8082 0 no-query no-digest connection-auth=on login=PASSTHRU round-robin proxy-only prefer_direct off nonhierarchical_direct off cache_peer_access 10.27.0.1 allow highpriodomains cache_peer_access 10.27.0.1 deny bulkupdatedomains cache_peer_access 10.28.0.1 allow bulkupdatedomains cache_peer_access 10.27.0.1 allow all cache_peer_access 10.28.0.1 allow all ------------------ I would like highpriodomains to go to Parent 1 (10.27.0.1) and only go to Parent 2 (10.28.0.1) when Parent 1 is detected dead. But when I see the logs on the Parents, I see requests to highpriodomains also getting load-balanced. Also, when either of the parent is detected dead, all traffic should go to the live Parent, while bulkupdatedomains can take a hit for the time while faster link Parent is down. Could someone please suggest the ACLs/configuration that I can put in place to achieve what I want to? Thanks in advance. Regards, Nishant
