Remember, there is only one stream going to the browser, and the browser is
only expecting one document per connection. HTML wasn't designed for that
type of communication. You probably want to use the meta tag that asks the
browser to resubmit it's request after a few seconds (I can't remember which
one, but you should be able to find it on the list). That way, the user's
browser will get the "Please wait..." with a request to resubmit it's
request in 10 seconds. It will then generate a separate document containing
"Finished" on the subsequent request. The key is one document per request.
