So its a fix for some 'smart' web apps naive coders which are known to
embed their port in absolute URLs when serving on a non-80 port.

That line makes Squid listen for requests coming back in to the back-end
port, and handles them as if they were coming in port 80 like they
should have.

Tomcat IIRC now ships with config that does similar things on outgoing
pages to fix them itself where it can. So you probably won't hit that
problem, but its worth knowing about.
