Perhaps I just don't get it. I just upgraded to 2.6.3 and then all of a sudden, I read baout this TPROXY feature. It enables client and server ip spoofing and it basically bypasses the cache (so as to make it really really transparent etc). So.. if I understand it correctly, the aim of tproxy is to fix all the shortcomings with that of a "normal" squid 2.5 version of transparent caching which will wreck havoc in some circumstances right?? How does this affect say clients behind NAT?? Thanks
