You should also have a cache_peer_access rule preventing circular forwarding in case both is having problems.. Someting like the following should work: cache_peer the_apache parent ... no-query originserver default cache_peer the_other_server parent ... no-query cache_peer the_other_server sibling ... name=other_server_sibling (note: no no-query on the sibling relation, only the parent relations) acl from_other_server src the_other_server cache_peer_access the_other_server deny from_other_server cache_peer_access the_other_server_sibling deny from_other_server The dual sibling & parent relation to the other server is needed so that ICP only acts in sibling mode, but that it's still used as a parent if the preferred web server is down.

Re: [squid-users] Squid as Acceleration Proxy in a Squid Cluster
1. your cache sibling configuration is wrong; you're not contacting any of the sibling. 2. use the proxy-only flag if you don't want squid to store cache hits from the siblings. try something like cache_peer sibling1 sibling 80 3130 proxy-only no-delay allow-miss name=sibling1 mike At 03:02 PM 5/9/2007, Marcel Alburg wrote: Hello, my Networks looks like Internet | [LB] -ha- [LB] | | +-+ | | | | [Squid + Apache] [Squid + Apache] All Hosts has running a webserver at 127.0.0.1:80 and a squid at the official IP Adresse on Port 80.
