# ASP Application_OnStart and Application_OnEnd Events

Complete Application Object Reference

## 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>

online now!
</p>
