DefaultHttpHandler Class

Note: This class is new in the .NET Framework version 2.0.

Represents the properties and methods of a default HTTP handler.

Namespace: System.Web
Assembly: System.Web (in system.web.dll)

public ref class DefaultHttpHandler : IHttpAsyncHandler, IHttpHandler
public class DefaultHttpHandler implements IHttpAsyncHandler, IHttpHandler
public class DefaultHttpHandler implements IHttpAsyncHandler, IHttpHandler

A DefaultHttpHandler object intercepts incoming requests in the HTTP pipeline when both request interception has been configured through Microsoft Internet Information Services (IIS) version 6.0 and no explicit httpHandlers bindings apply to the requested extension.

Request interception can be set up through the wildcard application mapping feature introduced in IIS 6.0. For more information, search the MSDN Library for information about using wildcard application maps to remap a URL.

The DefaultHttpHandler class implements the IHttpAsyncHandler interface to provide asynchronous request processing. For general information about HTTP handlers, see Custom ASP.NET Processing with HTTP Handlers. Additionally, for more information:

Classes can derive from the DefaultHttpHandler class to provide customized handling of requests. An asynchronous HTTP handler that is derived from the DefaultHttpHandler could override the BeginProcessRequest method to change how requests are processed.

A DefaultHttpHandler does not use ASP.NET errors. Existing content that uses IIS errors or a propriety ISAPI custom error mechanism would work unchanged.

The following code example demonstrates how to implement a customized HTTP handler by deriving from the DefaultHttpHandler class.

No code example is currently available or this language may not be supported.
