Examples

The following code example creates a WebProxy object and calls this method to get the proxy that is selected for a resource.

// The following method creates a WebProxy object that uses Internet Explorer's  
// detected script if it is found in the registry; otherwise, it 
// tries to use Web proxy auto-discovery to set the proxy used for
// the request.
void CheckAutoGlobalProxyForRequest( Uri^ resource )
{
   WebProxy^ proxy = gcnew WebProxy;
   
   // Display the proxy's properties.
   DisplayProxyProperties( proxy );
   
   // See what proxy is used for the resource.
   Uri^ resourceProxy = proxy->GetProxy( resource );
   
   // Test to see whether a proxy was selected.
   if ( resourceProxy == resource )
   {
      Console::WriteLine( "No proxy for {0}", resource );
   }
   else
   {
      Console::WriteLine( "Proxy for {0} is {1}", resource, resourceProxy );
   }
}
// The following method creates a WebProxy object that uses Internet Explorer's
// detected script if it is found in the registry; otherwise, it
// tries to use Web proxy auto-discovery to set the proxy used for
// the request.

public static void CheckAutoGlobalProxyForRequest(Uri resource)
{
    WebProxy proxy = new WebProxy();

    // Display the proxy's properties.
    DisplayProxyProperties(proxy);

    // See what proxy is used for the resource.
    Uri resourceProxy = proxy.GetProxy(resource);

    // Test to see whether a proxy was selected.
    if (resourceProxy == resource)
    {
        Console.WriteLine("No proxy for {0}", resource);
    }
    else
    {
        Console.WriteLine("Proxy for {0} is {1}", resource.OriginalString,
            resourceProxy.ToString());
    }
}

Remarks

The GetProxy method returns the URI that the WebRequest instance uses to access the Internet resource.

GetProxy compares destination with the contents of BypassList, using the IsBypassed method. If IsBypassed returns true, GetProxy returns destination and the WebRequest instance does not use the proxy server.

If destination is not in BypassList, the WebRequest instance uses the proxy server and the Address property is returned.
