HttpWebRequest::AllowAutoRedirect Property

Gets or sets a value that indicates whether the request should follow redirection responses.

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

public:
virtual property bool AllowAutoRedirect {
	bool get ();
	void set (bool value);
}

Property Value

Type: System::Boolean
true if the request should automatically follow redirection responses from the Internet resource; otherwise, false. The default value is true.

Set AllowAutoRedirect to true if you want the request to automatically follow HTTP redirection headers to the new location of the resource. The maximum number of redirections to follow is set by the MaximumAutomaticRedirections property.

If AllowAutoRedirect is set to false, all responses with an HTTP status code from 300 to 399 is returned to the application.

The Authorization header is cleared on auto-redirects and HttpWebRequest automatically tries to re-authenticate to the redirected location. In practice, this means that an application can't put custom authentication information into the Authorization header if it is possible to encounter redirection. Instead, the application must implement and register a custom authentication module. The System.Net::AuthenticationManager and related class are used to implement a custom authentication module. The AuthenticationManager::Register method registers a custom authentication module.

The following code example uses the AllowAutoRedirect property to allow the request to follow redirection responses.

// Create a new HttpWebRequest Object to the mentioned URL.
HttpWebRequest^ myHttpWebRequest = (HttpWebRequest^)( WebRequest::Create( "http://www.contoso.com" ) );
myHttpWebRequest->MaximumAutomaticRedirections = 1;
myHttpWebRequest->AllowAutoRedirect = true;
HttpWebResponse^ myHttpWebResponse = (HttpWebResponse^)( myHttpWebRequest->GetResponse() );
