Hello All, We have 5 squid servers and each squid server is configured to send requests from certain clients to cache_peer( cache_peer is a filter) and rest of the request passes as direct requests. We have disk caching at all servers and need to share disk caching among the five servers. How to configure all squid servers with sibling relationship and ensure the clients which are supposed to pass through filter(cache_peer) are not bypassed filter or passed as direct requests? Whether following configuration will achieve it? Please share your views. proxy1 configuration: client range: 172.16.1.0/24 and 10.0.0.0/8 cache_peer example.com parent 3128 7 no-query no-digest default name=filter acl peer src 172.16.1.0/24 cache_peer_access filter allow peer cache_peer proxy2 sibling 3128 7 no-query proxy-only round-robin cache_peer proxy3 sibling 3128 7 no-query proxy-only round-robin cache_peer proxy4 sibling 3128 7 no-query proxy-only round-robin cache_peer proxy5 sibling 3128 7 no-query proxy-only round-robin Thanks Senthil
