asp.net - Difference between HttpRequest, HttpWebRequest and WebRequest

Question

I was wondering if somebody explain the difference for the listed classes

Answer 1

They do different things.

WebRequest is the abstract base class for HttpWebRequest - you can't use it directly. It is the base class of other *Request classes (for FTP, File and other types of web requests). These classes are all used for getting resources (files) from the web.

There is also a WebClient class - probably the simplest to use of all the BCL classes designed to retrieve a resource from the Internet.

HttpRequest, on the other hand represents a request for a resource in an ASP.NET application - this is the server side of a Request.

The main difference is that HttpWebRequest is an HTTP client, and HttpRequest is server side to be used in an ASP.NET web application.
