I brought an old DNN site from 4.6.2 where everything was fully functioning, to 5.6.3. We have some in-house written batch upload modules that load the chosen documents into a session object as you select them, then upload them all by pulling them out of session and looping through them. This worked in 4.6.2, but no longer works in 5.6.3. From stepping through the code, I've found that my SessionID changes everytime I make a page request. Adding a catch for Session_Start and Session_End, I found out that every page request fires Session_Start multiple times, but never fires Session_End. Any help you can offer to get this module working (without telling me to "just rewrite it") would be greatly appreciated. If I haven't included enough information to help you troubleshoot, I'll look up anything I can to be of assistance.
