Can you just stay on the page and make the wait portion visible (and the
rest not visible) while the server is processing. One way to check for
completed process is to use cache. You can put something in cache while
processing, check for it and continue the wait page if the cache item is
still present. Once the operation is completed, clear the cache can
redisplay. Don't know if this helps or not.
