Looking in the achive, before 2.6, it looks like if you want to proxy for several servers, then you need to separate the traffic based on the host name part of the URL. I was hoping to separate traffic based on destination IP address, but perhaps someone will have a better idea? i.e. Proxy (has 2 IP addresses 1.2.3.4 and 1.2.3.5) 1.2.3.4:80 --> server 1 (2.3.4.5:80) 1.2.3.5:80 --> server 2 (2.3.4.6:80) I have Squid 2.6 currently, and was wondering if this had changed with the rewrite that affects reverse proxy config between 2.5 and 2.6. Currently I have all traffic proxied to 2.3.4.5 And a list of exceptions: cache_peer_domain server1 !www.example.com cache_peer_domain server2 www.example.com I have about ~1185 domains to add in this fashion, with more added routinely, so some sort of automated procedure is a given. Also I was concerned if a big list like this would impact performance. The only other approach that occurs is to run a second instance of Squid listening on the other IP address, which is probably what I'll do if no one has a better idea.
