In most web applications that has to eventually get a connection from a 
browser, the default behavior would be to get a connection send content 
and then disconnect.

Because of this it is almost impossible to have a true continuous status 
of any kind of activity.

A good option (but complex one) would be using AJAX. Asynchronous 
Javascript and XML. A simpler one would be to use an HTML  window of 
sorts and periodically update the state of the entire window (refresh) 
every 5 or more seconds.

To see a good example of this, go to dropload.com, create an account and 
send a file to someone (using their rules).

You will then see an upload screen that uploads and refreshes in the way 
I described.


Hope this helped...
Good luck!
