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.
