I have an HttpApplication object oUpdateClient(Winsock control) listening for network messages which fires the NetworkReceive() event. I need to raise an event or something in a specific Session that notifies the user that a certain type of message has arrived. I am using Forms Authentication and I assign a User object(ID,Name,etc.) to a session("SessionUser") variable. Note: All of the code mentioned above is in the Global.asax page.
