Im folgenden Beispiel wird der Inhalt aller Antwortheader in die Konsole geschrieben.

// Creates an HttpWebRequest for the specified URL.
HttpWebRequest^ myHttpWebRequest = dynamic_cast<HttpWebRequest^>(WebRequest::Create( url ));

// Sends the HttpWebRequest and waits for response.
HttpWebResponse^ myHttpWebResponse = dynamic_cast<HttpWebResponse^>(myHttpWebRequest->GetResponse());

// Displays all the headers present in the response received from the URI.
Console::WriteLine( "\r\nThe following headers were received in the response:" );

// Displays each header and its key associated with the response.
for ( int i = 0; i < myHttpWebResponse->Headers->Count; ++i )
   Console::WriteLine( "\nHeader Name: {0}, Value : {1}",
      myHttpWebResponse->Headers->Keys[ i ],
      myHttpWebResponse->Headers[ (System::Net::HttpRequestHeader)i ] );

// Releases the resources of the response.
myHttpWebResponse->Close();
