The WebRequest object represents an HTTP request. The methods and properties provide access to the incoming data, and allow you to prepare outgoing data.
You are most likely to use this in conjunction with the WebApplication.HandleSpecialURL event handler. This event handler supplies a parameter (Request As WebRequest) that you can use to process the incoming request and send out a reply.
