you could also try WCCP [1] as well;  that will transparently route 
traffic you define (eg. tcp80) to a cache.
you’ll probably want to have two interfaces on your caches for easier 
management;  and i’d put them in a separate vlan so you can add more 
if you need to (ie scale horizontally) later.

proxying http isn’t going to be as useful as it was, say, 5 years ago, 
as more and more of the web starts to move to using https now.
