title: How do I fully refresh the page in CodeIgniter?
body: <p>I am loading a form in an overlay.  The overlay has a separate controller and action to the page that invokes the overlay.</p>
  
  <p>On form submit, if successful, I simply want to reload the referring page that the overlay was loaded from.  I can get the referring page to load, but it places the content inside the overlay.</p>
  
  <pre><code>header("Location: www.example.com", true, 302);
  </code></pre>
  
  <p>does not work.</p>
  
  <p>Using the URL helper like this:</p>
  
  <pre><code>$url = $_SERVER['HTTP_REFERER'];
  redirect($url);
  </code></pre>
  
  <p>Also does not work.  Every time it loads in the overlay.  I am sad because of it.</p>
