9.5 Adding New Protocol Handlers

Adding handlers to support new protocols is trivial; simply implement a new set of derived types based on WebRequest and WebResponse, implement the IWebRequestCreate interface on your WebRequest-derived type, and register it as a new protocol handler with the WebRequest.RegisterPrefix( ) at runtime. Once this is done, any code that uses the request/response architecture can access networked resources using the new URI format (and underlying protocol).
