You can do wonderful things with that servers. I guess you are
talking in a forward squid schema. 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
