Remarks
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.
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.
