Brilliant !! 

Got it now, didnt notice that being set before. but that will do the trick.

There is also a HTTP_X_VIA being set sometimes, which reports the
hostname of the client machine. This variable isnt set on every request
though.

There is also a HTTP_X_VARNISH variable set as well, which is just a
number.  Any idea what this one does ?
