title: Send url with web client
body: <p>When I tried to the following link url on address bar, response is "OK"</p>
  
  <pre><code>http://ww.exmaple.com.tr/webservices/addlead.php?first_name=" + r.Name + "&amp;last_name=" + r.Surname + "&amp;phone=" + r.Telephone + "&amp;hash=" + r.HashCode
  </code></pre>
  
  <p>But when I tried to link with webclient like the below, response is "AUTH ERROR" </p>
  
  <pre><code>string URI = "http://ww.exmaple.com.tr/webservices/addlead.php";
  string myParameters = "first_name=" + r.Name + "&amp;last_name=" + r.Surname + "&amp;phone=" + r.Telephone + "&amp;hash=" + r.HashCode;
  
  using (WebClient wc = new WebClient())
  {
    wc.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
    string HtmlResult = wc.UploadString(URI, myParameters);
  }
  </code></pre>
