The WebException class is thrown by classes descended from WebRequest and WebResponse that implement pluggable protocols for accessing the Internet.

When WebException is thrown by a descendant of the WebRequest class, the Response property provides the Internet response to the application.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
