RequestNotification Enumeration
Indicates when events and other life-cycle events occur while a HttpApplication request is being processed.
This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

The RequestNotification enumeration is used with the CurrentNotification property of the HttpContext class to determine what event in the pipeline is currently processing. To determine when all the handlers for a specific event of the HttpApplication instance have finished processing, use the IsPostNotification property.
The RequestNotification type is introduced in the .NET Framework 3.5. For more information, see .NET Framework Versions and Dependencies.
The following example shows how to use the RequestNotification enumeration with the CurrentNotification property to determine which event of the current HttpApplication instance is processing the request.
