Hi. I have a client that I've developed a solution for using RadUpload. We've discovered just recently that there seems to be a barrier somewhere around 30 megabytes. I flipped over to another solution I have that uses RadUpload (different server) and am experiencing the same thing. Both servers are Server 2008, and I've modified the web.config file on both servers as follows:
So both servers are configured for a maximum 100MB file and 60 minutes of upload.
I have tested files of various size between 1MB and 28MB and they upload fine - everything, including my ProgressArea, works. When i upload a file above 30 MB, though, my ProgressArea doesn't display, and after about 2 minutes (regardless of connection speed), I get redirected to a 404 or timeout page.
I've tested this on everything from a 512kb (up) connection to a 7mb (up) connection and the barrier seems to be right around 30 megabytes, consistently.
I am running these inside UpdatePanels using AJAX but have added a PostBackTrigger to my upload button to trigger a full page postback when it is clicked.
Hopefully that's enough info to get some help here. I've seen several people with issues related to the web.config settings and the ajax postback settings, but I think I have both of those dealt with. I'd appreciate your assistance.
