title: How to capture HTTP full headers with watir
body: <p>I need to capture HTTP response coming after the request made.
  I have tried with "net/http" gem but it is not giving me full response header.
  the code I have tried is </p>
  
  <pre><code>uri = URI("http:/example.com")
  res = Net::HTTP.get_response(uri)
  res.to_hash
  </code></pre>
  
  <p>I am getting some response headers but not full headers, I have checked the same request in firebug and it is giving some extra headers what I am getting by my code</p>
  
  <p>Can any one help me out for this to get full HTTP response headers, or any trick to do that by invoking browser.</p>
