title: Issue with header location and http response code
body: <pre><code>    $models = new Models();
      $myModel = $models-&gt;getURL($modUrl, 1);
      if (!$myModel) {
          header('Location: /our-models', true, 404);
      }
  </code></pre>
  
  <p>If I use <code>header('Location: /our-models', true, 404);</code> nothing happens (the execution of the page continue), but <code>header('Location: /our-models');</code> do the redirect.</p>
  
  <p>Something is wrong with my redirect?</p>
  
  <p>Thanks.</p>
