Exception typeCondition


The request scheme specified in requestUri is not registered.


requestUri is a null reference (Nothing in Visual Basic).


The caller does not have permission to connect to the requested URI or a URI that the request is redirected to.

The CreateDefault method returns a WebRequest descendant instance based on only the scheme portion of a URI.

For example, when a URI beginning with http:// is passed in requestUri, an HttpWebRequest is returned by CreateDefault. If a URI beginning with file:// is passed instead, the CreateDefault method will return a FileWebRequest.
