We have a page with a RadUpload (an instance of our own descendant of RadUpload). Someone has reported that it is choking on a 50 megabyte file. I have been tasked to investigate this. It appears that we have a RadUpload in a user control with Localization.Select =Browse. There does not appear to be any RadProgressManager or RadProgressArea.
According to "http://www.telerik.com/products/aspnet-ajax/upload.aspx
"The Telerik ASP.NET Upload control now features a new HttpHandler specially designed for monitoring the process and updating its progress. As a result upon a request for progress update the server is not hit as the page does not go through the complete page lifecycle as this is not needed. This significantly reduces the server load and data transfer. "
How do I determine if this HttpHandler is being used?
