GlobalProxySelection Class

NOTE: This class is now obsolete.

Contains a global default proxy instance for all HTTP requests.

Namespace: System.Net
Assembly: System (in system.dll)

[ObsoleteAttribute("This class has been deprecated. Please use WebRequest.DefaultWebProxy instead to access and set the global default proxy. Use \'null\' instead of GetEmptyWebProxy. http://go.microsoft.com/fwlink/?linkid=14202")] 
public class GlobalProxySelection
/** @attribute ObsoleteAttribute("This class has been deprecated. Please use WebRequest.DefaultWebProxy instead to access and set the global default proxy. Use \'null\' instead of GetEmptyWebProxy. http://go.microsoft.com/fwlink/?linkid=14202") */ 
public class GlobalProxySelection
ObsoleteAttribute("This class has been deprecated. Please use WebRequest.DefaultWebProxy instead to access and set the global default proxy. Use \u0027null\u0027 instead of GetEmptyWebProxy. http://go.microsoft.com/fwlink/?linkid=14202") 
public class GlobalProxySelection
Not applicable.

The GlobalProxySelection stores the proxy settings for the default proxy that WebRequest instances use to contact Internet sites beyond the local network. The default proxy setting is initialized from the global or application configuration file, and can be overridden for individual requests or disabled by setting the HttpWebRequest.Proxy property to the result of the GetEmptyWebProxy method.

The proxy settings stored in GlobalProxySelection are used by any WebRequest derived objects that support proxies and have their Proxy property value set to a null reference (Nothing in Visual Basic) (the default). Proxies are currently supported by FtpWebRequest, HttpWebRequest, and WebClient.

Note   Changes to the GlobalProxySelection after a request is made are not reflected in a WebRequest.

The following code example sets the GlobalProxySelection for an HTTP proxy named "webproxy" on port 80.

Uri proxyURI = new Uri("http://webproxy:80");
 GlobalProxySelection.Select = new WebProxy(proxyURI);


Uri proxyURI = new Uri("http://webproxy:80");
GlobalProxySelection.set_Select(new WebProxy(proxyURI));
