Are you sure that #3 is taken care of? Your browsers might be sending the
referral header, but your cache may not be propogating it if you have the
"Paranoid" or "Standard" set. From my experience (1.2.beta23) while the
"standard" option says it will pass the Forwarded-For header unchanged, it
actually take the input from the forwarded_for setting.

Not that I'm complaining - I actually LIKE that bug, since it saved me from
writing that functionality in myself.

Anyway, you should actually take a look at the headers of a request coming out
of your Squid.
