Defines the contract that HTTP asynchronous handler objects must implement.
Assembly: System.Web (in System.Web.dll)
Thetype exposes the following members.
|BeginProcessRequest||Initiates an asynchronous call to the HTTP handler.|
|EndProcessRequest||Provides an asynchronous process End method when the process ends.|
|ProcessRequest||Enables processing of HTTP Web requests by a custom HttpHandler that implements the IHttpHandler interface. (Inherited from IHttpHandler.)|
An class can be associated with a file name extension or a particular URL by a configuration file, in the httpHandlers configuration section. The ASP.NET infrastructure will then instantiate and call the handler when the corresponding request is received. Alternatively, the handler can be defined in an .ashx file and when the corresponding request is received for the .ashx file the hander will be executed.
