I tend to think that a subscriber could be a Windows Service running
on the web server - and, which gets initialised before any firewall
(?), so that is not an issue - and rebuilds the client web page
(selectively) and refreshes it i.e it does nothing to the structure of
the page and therefore, the underlying code should carry on working.

I have some idea of how this might work but not enough to demonstrate
it right away.
