Hello All, We have three squid servers for testing and for our requirement we configured as follows, squid1.conf cache_peer squid2 sibling 80 3130 squid2.conf cache_peer squid3 sibling 80 3130 allow-miss We are getting the following error "Valid document was not found in the cache and 'only-if-cached' directive was specified", When squid1 makes request to squid2 and in turn squid2 makes request to squid3 The setup works fine when we use allow-miss option. We may include few other squid servers as sibling in future. In this case allow-miss tag will cause any forwarding loop? or it causes any trouble? Can any one explain how allow-miss? Thanks Senthil
