Remarks

Use the LoggedOut event to provide additional processing, such as closing database connections or cleaning up per-user cached data, after the user has logged out of a Web site.

For more information about how to handle events, see Handling and Raising Events. Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnLoggedOut method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

When overriding OnLoggedOut(EventArgs) in a derived class, be sure to call the base class's OnLoggedOut(EventArgs) method so that registered delegates receive the event.
