Name
HttpWebRequest
Synopsis
This is a subclass of WebRequest. .NET uses this
subclass to request documents from
the http and https URI schemes
(RFCs 2616 and 2818, respectively). An instance of this type is
returned by WebRequest.Create( ) when a URI
starting with the http:// or
https:// prefix is passed in. Since that
method’s return value is
WebRequest, cast it to
HttpWebRequest if you need access to any of the
methods or properties that are unique to this class (and the HTTP or
HTTPS protocol).
The properties on this type correspond directly to the headers
documented in the RFC standard documentation; see that document for
details regarding their contents. Note that because these headers are
sent as part of the HTTP request, any modification of the headers
must be done before the request is sent to the remote host. (Calling
either GetResponse( ) or
BeginGetResponse( ), the asynchronous version of
GetResponse( ), sends the request.)
When a WebRequest encounters an error, a
WebException is thrown.
