.NET Framework 3.0
| Name | Description | |
|---|---|---|
| AcquireRequestState | Occurs when ASP.NET acquires the current state (for example, session state) that is 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 in the HTTP pipeline chain of execution when ASP.NET responds to a request. |
| Error | Occurs when an unhandled exception is thrown. |
| LogRequest | Occurs just before ASP.NET performs any logging for the current request. |
| MapRequestHandler | Occurs when the handler is selected to respond to the request. |
| PostAcquireRequestState | Occurs when the request state (for example, session state) that is associated with the current request has been obtained. |
| PostAuthenticateRequest | Occurs when a security module has established the identity of the user. |
| PostAuthorizeRequest | Occurs when the user for the current request has been authorized. |
| PostLogRequest | Occurs when ASP.NET has completed processing all the event handlers for the LogRequest event. |
| PostMapRequestHandler | Occurs when ASP.NET has mapped the current request to the appropriate event handler. |
| PostReleaseRequestState | Occurs when ASP.NET has completed executing all request event handlers and the request state data has been stored. |
| PostRequestHandlerExecute | Occurs when the ASP.NET event handler (for example, a page or an XML Web service) finishes execution. |
| PostResolveRequestCache | Occurs when ASP.NET bypasses execution of the current event handler and allows a caching module to serve a request from the cache. |
| PostUpdateRequestCache | Occurs when ASP.NET completes updating caching modules and storing responses that are used to serve subsequent requests from the cache. |
| PreRequestHandlerExecute | Occurs just before ASP.NET begins executing an event handler (for example, a page or an 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 event 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 event handler (for example, a page or an XML Web service). |
| UpdateRequestCache | Occurs when ASP.NET finishes executing an event handler in order to let caching modules store responses that will be used to serve subsequent requests from the cache. |
