I've been developing a web-based application revolving around a SQL dB, and up until last week, it was working just peachy. However, within the last week, it seems to have entirely ceased to be able to initiate a session. The app needs to start a session, to gather some session info based on a stored procedure. Sessions continue to start all right for another app on the same server, which retrieves the info needed from the stored procedure without incident. If I go to this page, then back to my app, the session is maintained and the app works. If I close out of the browser, and come back into my app fresh, it pulls up SQL errors which we've narrowed down to the missing session variables. The code on this app, and the one that is working, regarding session is identical. Both have @ENABLESESSIONSTATE = True and Response.Buffer = True. Does anyone have any idea why this is happening and how to fix it? I've searched all over the web for any clue, and consulted with another developer, and there don't seem to be any answers.
