title: Send POST HttpWebRequest and don't need to receive response
body: <p>I send a POST request by this way:</p>
  
  <pre><code>HttpWebResponse res = null;
  HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(url);
  req.Method = "POST";
  req.CookieContainer = cookieContainer;
  req.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.1; de; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3";
  req.ContentType = "application/x-www-form-urlencoded";
  ASCIIEncoding encoding = new ASCIIEncoding();
  byte[] loginDataBytes = encoding.GetBytes(requestCommand);
  req.ContentLength = loginDataBytes.Length;
  Stream stream = req.GetRequestStream();
  stream.Write(loginDataBytes, 0, loginDataBytes.Length);
  stream.Close();
  //line below is my way to send request, but it return a response.
  res = (HttpWebResponse)req.GetResponse();
  </code></pre>
  
  <p>I just want to send request to WebServer and I don't want to receive reponse. It wastes time and bandwidth. Are there anyway to do that? </p>
  
  <p>Thank you very much!</p>
