How do I cancel a form submit that is in progress?
I have a form that uploads a file and pops up a progress meter (I use setInterval() to run the monitor process). In the meter, I'd like to have a cancel button. So let's say the file takes a whopping 10 minutes to upload and at about minute 5 the user decides to hit the cancel button and terminate the upload. How do I instruct the form to stop uploading the file, or is this not possible?
