Best you can probably do is to have a timer fire every 15 - 20 seconds, check if an update has been made, if so send the new information. This is how Gmail "Drafts" works. Otherwise, maybe you can store the form values in a JavaScript object onchange, then onunload submit the object. From what I've read onunload should complete as fast as possible, so, I'm not exactly sure you want to attach an Ajax Post to this event.

I looked into onunload but from what I can asertain by the time that event fires the form already no longer exists and can't be submitted to the server. Doing an AJAX post whenever the form changes isn't acceptible because that would generate too much database traffic, so I'm kind of stuck. I did suggest preservign the data in a cookie instead of the database but that is apparently not acceptable either. Is there some other way I could have the form submitted when the user leaves the page?
