Thx for the info. What I was trying to explain, was : For example if we take xxxsite1.com and xxxsite2.com, when a user try to access these 2 sites, squidguard will return an error.php with a specific msg and for example a gif file. What I was wondering, was : will this gif be stored two times in the cache? (as an object of xxxsite1 and as one of xxxsite2) Btw, I received the new hardware and configured it using the hints you gave me (reiserfs, aufs, ...) and with is a part of the tweeking. But the improve in the perf are significant (this morning we reached 92req/s with only 50% cpu utilisation on one cpu). Thx!!!

This url is then fetched by squid, and it's own freshness info, will apply as to whether squid will cache it and related objects or not. > If so, this would mean that the error page is cached many times as > different sites... > Can't understand that argument. But remember also, squid does not know about 'pages' M.
