An IWebProxy that every call to HttpWebRequest.GetResponse uses.


The value specified for a set operation was Nothing.


The caller does not have permission for the requested operation.

The Select property sets the proxy that all WebRequest instances use if the request supports proxies and no proxy is set explicitly using the Proxy property. Proxies are currently supported by FtpWebRequest and HttpWebRequest.

The following code example sets the Select property to the empty proxy.
