Request loops only occur if Squid is listening to port 80. If Squid
isn't listening to port 80 and you have no HTTP server listening to port
80 then Squid will automatically mark 127.0.0.1 as a bad IP address and
skip it.

Some users without a proxy but with a local web server on their machine
(Personal Web server or the like) may also get very confused when they
randomly receive their own web pages when they request
www.amityworld.com....
