I guess you are not using MD5 authentication shcema, if you so please clarify since MD5 needs special attention. I suggest you this: - Place a balancer, like ultramonkey3, with persistence src (if using MD5) or RR (any variant for other) with this you can take ofline any squid for maintenance without problem, - inside each squid (i suggest you 3.1) place 2 squids (lets A and B). So intotal you will get 6 squids, 2 each box, squid A will face to customer, squid B will face to lookpabck. - install an icap server to do the AV. - each squid A will be brother each other, each squid B will be brother each other. ICP protocol. this will warrant you that squid A cache content is always clean, and squid B is only acting to speed up and save bandwith. Let me know your thinking LD http://www.twitter.com/ldlq
