Public Events

AcquireRequestState	Occurs when ASP.NET acquires the current state (for example, session state) associated with the current request.
AuthenticateRequest	Occurs when a security module has established the identity of the user.
AuthorizeRequest	Occurs when a security module has verified user authorization.
BeginRequest	Occurs as the first event in the HTTP pipeline chain of execution when ASP.NET responds to a request.
Disposed	Adds an event handler to listen to the Disposed event on the application.
EndRequest	Occurs as the last event to in the HTTP pipeline chain of execution when ASP.NET responds to a request.
Error	Occurs when an unhandled exception is thrown.
PostRequestHandlerExecute	Occurs when the ASP.NET handler (page, XML Web service) finishes execution.
PreRequestHandlerExecute	Occurs just before ASP.NET begins executing a handler such as a page or XML Web service.
PreSendRequestContent	Occurs just before ASP.NET sends content to the client.
PreSendRequestHeaders	Occurs just before ASP.NET sends HTTP headers to the client.
ReleaseRequestState	Occurs after ASP.NET finishes executing all request handlers. This event causes state modules to save the current state data.
ResolveRequestCache	Occurs when ASP.NET completes an authorization event to let the caching modules serve requests from the cache, bypassing execution of the handler (the page or XML Web service, for example).
UpdateRequestCache	Occurs when ASP.NET finishes executing a handler in order to let caching modules store responses that will be used to serve subsequent requests from the cache.
