ASP. NET-how: add the logon button to the ASP. NET webpage

If the user has been authenticated, a button is displayed in the loginstatus control. You can click this button to log out of the application.

Note: by default, ASP. NET membership and forms authentication are configured to be used with pages named login. aspx. You can change the default logon Page name by setting the loginurl attribute of the <forms> element in the application configuration file.
