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!

That is the default behavior in HTTP v1.0 and older.  The default behavior
in HTTP v1.1 is to keep the connection open between requests to the same
server.

Javascript alone cannot do that.  The closest you can get is to host the
status bar in a separate HTML frame, and have that page run a timer that
periodically sends a status request to the server to get new HTML for the
status bar.

There is no way to make a browser do that.  There is nothing in HTML to tell
the browser to send a portion of a file.  It is an all-or-nothing operation.
To have better control over the connections, you would have to write a
custom Java/Flash applet or browser plugin to handle that on behalf of the
HTML page.
