Remarks

The WebResponse class is the abstract base class from which protocol-specific response classes are derived. Applications can participate in request and response transactions in a protocol-agnostic manner using instances of the WebResponse class while protocol-specific classes derived from WebResponse carry out the details of the request.

Client applications do not create WebResponse objects directly; they are created by calling the BeginGetResponse method on a WebRequest instance.

Notes to Inheritors

When you inherit from WebResponse, you must override the following members: ContentLength, ContentType, Close, GetResponseStream, Headers, and ResponseUri.
