title: How to get last url from HttpClient?
body: <p>OK, i was recently switch to .NET framework 4.5 and start using HttpClient instead of HttpWebRequest &amp; Response.
  I really love that async/await style but i don't know how to get the redirected url after a POST / GET request.</p>
  
  <p>With HttpWebResponse i can use .ResponseUri attribute</p>
  
  <pre><code>HttpWebRequest request = (HttpWebRequest)WebRequest.Create ("http://www.google.com");
  HttpWebResponse response = (HttpWebResponse)request.GetResponse ();
  string responseURI = response.ResponseUri;
  </code></pre>
  
  <p>Took me 3 hours of searching and i still can't get it done:(</p>
