This is a general-purpose class that gives you direct access to the HTTP response information, which could be used for encapsulation of HTTP-specific information. One use of this class is to support services implemented in accordance with the Representational State Transfer (REST) architecture.
This class enables you to support the following scenarios:
Controls whether an entity body is transmitted.
Allows HTTP header (key, value) pairs to be set for each response.
Varies the status code and status description used for each response.
This class can be used by HttpTransportBindingElement and related classes.
