But that is as far as Squid can go. as you are far more familiar with the protocol details just a quick question about your suggestion: for me cache2 terminates the http connection, so all connections to web-servers are made by cache2 as the "face" of all traffic. Correct ? In case we would set up direct routes from three public IPs on Cache2 to three corresponding IPs on the interfaces of the multi-WAN-router would that speed up a single http/https/ftp download (Cache2->Cache1) using your feature and tcp_outgoing_address ?
