Hi, Now I have an inner squid namely squid-1 and outer squid namely squid-2. squid-1 has a squid-2 as parent: cache_peer squid-2.domain parent 8080 0 no-query default never_direct allow all Please tell me if I understand what that means: a) Client behind (only) squid-2 ask for object "A", because is not on his own cache, ask to the internet, retrieves the object and save it on his own cache. b) When client behind squid-1 ask for an object "A" squid-1 looks fisrtly at his own cache and if it's hasn't it, redirects the petition to squid-2. c) Then squid directly ask for object "A" on internet, but doesn't look at his own cache, because of no-query option in squid.conf os squid-1. d) squid-2 retrieves object "A" and save it on his own cache. If the above is right, squid-2 would be working twice, wouldn't it? In that case, no-query would not be so useful. Please fix me if I'm wrong -- -- Open Kairos http://www.openkairos.com Watch More TV http://sebelk.blogspot.com Sergio Belkin -
