SessionStateModule.Start Event

The event that occurs when a session is created.

Namespace:  System.Web.SessionState
Assembly:  System.Web (in System.Web.dll)

public event EventHandler Start

The Start event is raised at the beginning of a request when a new session is started. A new session is started if a request is made that does not contain a session identifier, the session identifier is invalid, or the session associated with a session identifier has expired.

The Session_OnStart event is used to perform any initialization work for a session such as setting up default values for session variables.

You can specify a handler for the Start event by adding a public subroutine named Session_OnStart to the Global.asax file.

For more information about the Global.asax file, see Global.asax Syntax.

The following code example shows the contents of a Global.asax file with the Session_OnStart and Session_OnEnd events defined.

<script language="C#" runat="server">
public void Session_OnStart()
{

}

public void Session_OnEnd()
{

}
</script>
