I have a file upload form that has a target of an IFRAME. The IFRAME does the upload and then updates the parent window with the new file name. If there are file or database errors along the way, those get reported to the parent windows status div as well.
My problem is that if the file is too large, the web server returns error 414 (IIS7) and when this is ready for production and the iframe is hidden, there will be nothing to update my status box.
I've googled around for a solution to have the IFRAME send it's status code to the main window (unlikely) or to have the parent window be able to detect the HTTP status code of the IFRAME (hopefully more likely), but everyone seems to respond to the original poster that you cannot get details about the IFRAME outside of your domain --- but I'm inside of my domain, so I'm hoping for the best!
