As far as I know browsers don't expose progress info to scripts, but some of them display upload progress in their own progress bar in the status bar at the bottom of the window. Have you tried using the new Yahoo Mail user interface? Check out the file attachment function when composing a message. I tried it with IE and could see the progress of the upload, but Firefox had an all or nothing deal, where the progress bar went from 0% from 100% once the file upload was done.

I'm implementing a site that requires the uploading of files that may be big (10 megabytes or more) and/or may be on a slow connection. Is there any way to implement a kind of progress-bar display?
I tried implementing something via Ajax but getting the actual upload progress information from the server has proved elusive. Any help would be greatly appreciated.
