HttpApplication Events
Visual Studio 2010
The HttpApplication type exposes the following members.
| 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 | Occurs when the application is disposed. |
|
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 | Infrastructure. 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 finishes updating caching modules and storing responses that are used to serve subsequent requests from the cache. |
|
PreRequestHandlerExecute | Occurs just before ASP.NET starts 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 finishes 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. |
