Thanks Christian,
I tried to implement it this way, but found implementing
activateExternalPage on every page a bit of an overkill!!
With my solution it 'just works' for every (GET) page with no additional
work. But surely there is a better way to do it than both of these.
PS I've removed the hack of using DescriptionReceiver to retrieve
HttpServletRequest from WebRequest (I found I can just inject
HttpServletRequest).
