to concur with the other replies to date, squid would appear to be the 
best solution for you.

add to that "smart" DNS logic (based on request IP, it is not that 
difficult to let squid hand off requests for most objects (particularly 
static) to be served by the closest server (IP-wise, not geographic) by 
your servers.

a quick google search has come up with four examples relating to this 
directly. i'm sure you'll be able to find one to fit your infrastructure.
