You're not listening.
There is no way to accomplish this via a the Common Gateway Interface(a Browser). Meaning client/server communication via a browser is turn based. The browser says something, the server says something back. And then
You CAN accomplish this, but it'll require your clients download some kind of plugin or program.
I also asked a few monks in the c/b, and chromatic pointed out, like i've been saying, that there is no way having the server send status of the request to the client, within the constraints of the HTTP spec.
Which brings me back to what i said before, you can do it if your clients download some kind of program or plugin.
I will mention the method that the IndigoPerl folks used, but that would require you have 2 browser windows open, or some kind of frames(HTML frames) configuration, but it still wouldn't provide for resuming(incremental turn based upload like you suggested).
chromatic mentioned something like that being possible with Netscape, if the Netscape folks are able to finish it, but don't hold your breath.
I would like to apologize in advance to chromatic if i misunderstood or miscommunicated anything.
Perl for IE via ActivX sounds like an option, but i don't know too many casual users who have perl installed.
Another option might be some kind of java applet, or even a Macromedia Flash(yes it is possible) plugin.
