        string spoofedIP = "192.168.0.1";

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
        request.Method = "GET";
        request.Headers.Add("X-Forwarded-For", spoofedIP);

        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        Console.WriteLine(response.StatusCode);
