The authentication is handled by the app rather than standard http-auth
which is one of the reason's that I'm attempting to cache particular
parts of the site rather than all of it which would be much easier.

Having used the firefox live headers tool I see pretty much what the
squid logs were telling me :-
http://www.xxxxx.xxx:8080/1242167/2184304
