The Application_OnStart and Application_OnEnd Events

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.

Syntax

<script language="vbscript" runat="server">

Sub Application_OnStart
. . . 
End Sub

Sub Application_OnEnd
. . . 
End Sub

</script>

Examples

Global.asa:

<script language="vbscript" runat="server">

Sub Application_OnEnd()
Application("totvisitors")=Application("visitors")
End Sub

Sub Application_OnStart
Application("visitors")=0
End Sub

Sub Session_OnStart
Application.Lock
Application("visitors")=Application("visitors")+1
Application.UnLock
End Sub

Sub Session_OnEnd
Application.Lock
Application("visitors")=Application("visitors")-1
Application.UnLock
End Sub

</script>
