title: HttpWebRequest doesn't work in a web page
body: <p>I have always used this code to donwload the html source from a web page:</p>
  
  <pre><code>private string GetHtml(string url)
  {
    HttpWebRequest web = (HttpWebRequest)WebRequest.Create(url);
    web.Method = "GET";
    WebResponse resp = web.GetResponse();
    Stream istrm = resp.GetResponseStream();
    StreamReader sr = new StreamReader(istrm);
    string html = sr.ReadToEnd();
    sr.Close();
    resp.Close();
    return html;
  }
  </code></pre>
  
  <p>But it returns an empty string when url has this value:</p>
