Application_OnStart Event
The Application_OnStart event occurs before the first new session is created (when the Application object is first referenced).
This event is placed in the Global.asa file.
Note: Referencing to a Session, Request, or Response objects in the Application_OnStart event script will cause an error.
Application_OnEnd Event
The Application_OnEnd event occurs when the application ends (when the web server stops).
This event is placed in the Global.asa file.
Note: The MapPath method cannot be used in the Application_OnEnd code.
