title: UIWebView capturing the response headers
body: <p>I searched/googled a lot but could not get the answer on how to capture HTTP response headers in <code>UIWebview</code>. Say I redirect to user to registration gateway(which is already active) in UIWebview on App Launch and when user finishes the registration, the app should be notified with the successful unique id assigned to the user on registration which is passed back in HTTP Response Headers.</p>
  
  <p>Is there any direct way to capture/print the HTTP Response headers using <code>UIWebview</code>?</p>
