title: Get network.request response headers in lua
body: <p>I’m using network.request like this:</p>
  <pre><code>network.request( fullUrl, &quot;POST&quot;, networkListener, params)
  </code></pre>
  <p>and receiving the response in my network listener as such:</p>
  <pre><code>local function networkListener( event )
      if ( event.isError ) then
          response = {};
      else
          response = json.decode(event.response);
      end
  end
  </code></pre>
  <p>I am receiving the body response of the request but <strong>I want to receive the request’s response headers as well. How can I achieve this?</strong></p>
  <p>Thanks a lot!</p>
