Just have the firewall return a HTML document
that says "please wait while scanning" with
a client-side pull to get the same document
again every 5 seconds.

That can't be done by the firewall - the web browser asked for a file and
expects either an OK followed by a data stream or an error code. Without
redefining the HTTP protocol - and getting the browsers to understand your
extension - there's no way to make this work.
