(with BSD) You basically do a function call to the TCP stack to see what the
original IP address you accepted the connection on. Squid
would then translate that to 'GET http://ip-accepted-on/path/file'

Squid works fine under linux if you use the 'httpd_accel virtual 80'
option in your squid.conf, but I think that BSD does it differently...
there was a patch posted a short while (a month, I guess) ago...
