title: How to get the current URL in http.go?
body: <p>I'm using <code>http.NewRequest</code> to make several http requests ( obviously ). Now I need to make request and extract some query strings  from the final URL ( there is a redirect ) . </p>
  
  <p>So the question is how can I find the URL (if the final URL if the client  was redirected ) ? There is no such field in <a href="http://golang.org/pkg/net/http/#Response" rel="nofollow">Response</a>.</p>
  
  <p>Please note that I don't need to stop the redirect... only to find what's the URL after request</p>
