title: Invalid URI: The Authority/Host could not be parsed from very long url
body: <p>This is the actual url to a Youtube video, at this moment if you copy to your chrome browser you may watch the video. But when I try to create a request I get <code>UriFormatException</code>.
  What am I doing wrong?</p>
  
  <pre><code>HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
  </code></pre>
