The cache_peer_access options in Squid can be used with any of the
request ACL, and cache_peer can have multiple entries.

As long as you can define explicitly who is meant to be going where it
can be written as ACL in squid.conf and the same request from different
people routed anywhere.

May take a little getting your head around the possibilities, but once
you do you will find it an easier way to run things.

Arbitrarily complex:
  ie
   user B it goes to server B no matter the source
   machines in subnet A aways go to server A
   user C from machine D goes to Server B
etc, etc.

add on top external ACL feature, which can pull settings from a database
or arbitrary information source. And you have a real-time plug-n-play
access system for any number of source servers.
