Public Interface IHttpAsyncHandler
Inherits IHttpHandler
Dim instance As IHttpAsyncHandler
public interface IHttpAsyncHandler : IHttpHandler
public interface class IHttpAsyncHandler : IHttpHandler
public interface IHttpAsyncHandler extends IHttpHandler
public interface IHttpAsyncHandler extends IHttpHandler
An IHttpAsyncHandler 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.
