What we do is have a page generated immediately with a "Processing, Please
Wait" message. In it's header we put a redirect to a Get on another servlet
and a 'refresh' setting of 10 seconds. This causes the page to check with
the new servlet every 10 sec or so (you can even put the current time so
that the user sees the page changing).
When the processing servlet completes its stuff we store the result in a
database table. The second servlet which is being checked every 10 seconds
looks in the database for the result, and when it finds it, it displays it
and looses the refresh.
