----------------------------------------------------------- From: Sitaraman Message 2 in Discussion Hi Probably u r trying to prevent "ultiple Logins from the same user id"!!!! Right!!!! Ok! Session_OnEnd has problems in StateServer & SQL based Session Mgmt. Check these out for the problem description and solution "Preventing Multiple Logins in ASP.NET" by "Peter A. Bromberg" : "The main issue is that if you put some sort of "lock" on the user record because somebody has logged in, and then they close their browser and you don't have a reliable way of determining that their session has expired so you can remove the lock, you are likely to get calls to your Tech Support desk from users complaining they cannot log in! (trust me, I have good reports that this has happened...) The big problem, it turns out, is that with StateServer and SQL Server Sessions, the Session_End event in Global is never fired. Only InProc mode fires this. So in order to avoid Tech Support coming after us with hatchets and knives, we would need to come up with some sort of reliable surrogate for the Session_End event. Robbe took off on his own angle here and wrote an excellent article about using the Cache class to handle some of these issues. You can read it here. Robbe also discusses how to use the callback mechanism in the Cache class to handle the situation where the item is removed from the Cache. In fact, he's determined that this even fires when the ASP.NET worker process recycles under normal conditions (such as when specified in machine.config), thereby enabling us to serialize Cache items to a database for later rehydration."

Morris : "In ASP.NET, the Session_OnEnd event appears to fire fairly consistently when using InProc as the Session management option. However, if the ASP.NET worker process recycles, you are likely to get inconsistant results. The Session_OnEnd event doesn't fire properly when utilizing State Server or SQL Server as the State management option. For many of us, this creates a real problem" Link : http://www.eggheadcafe.com/articles/20030416.asp Related articles.
