[DUG] HTTP Upload Progress

[Richard Vowles]

The way I implemented this (in a Java web server) was that once the form was
submitted, an ajax request was fired off in the background and repeatedly
asked the server how the file upload was progressing, and updated the amount
of colour in a progress bar. The upload was attached to the session, so  the
ajax call was able to grab the info structure from the session and query it
(as the file upload specifies how big something is and as the upload is
happening, you can just specify in the structure how much you had received).
