Asynchronous file uploads is quote popular feature in modern AJAX web-applications. However standard AJAX classes (XmlHttpRequest) does not have capabilities to process or send files selected with "file dialog" (input type="file"). This article contains example application (trivial file-sharing service, like rapidshare, megaupload or yousendit) which uses embedded frames (IFRAME) to upload file.

Good topic, but the article is really short and don't give any deep value informations, only source code.

Well, this is just an example, not a tutorial, so the longest part of it is source code...

dude, iframes != ajax
iframes have been around since animated gifs, blinking text and all the other crap

jiminoc,
Actually iframes, especially dynamically generated hidden iframes, are part of ajax. I would recommend the book "Professional Ajax" that provides insight to many of Googles' Ajax driven sites.
