title: Import an HTML file from inside a Twig template
body: <p>I want to import an HTML file from inside a Twig template. The HTML file is located at <code>/var/files/5</code> (with no extension). And I render the template like this:</p>
  
  <pre><code>$path = $_SERVER['DOCUMENT_ROOT'] . '/../var/files/5';
  $content = $this-&gt;get('templating')-&gt;render('ProConvocationBundle:Default:definitive-view.html.twig', array('path' =&gt; $path));
  </code></pre>
  
  <p>Inside the Twig template I import the HTML file like this:</p>
  
  <pre><code>{% include path %}
  </code></pre>
  
  <p>but it is not finding the path: <em>Unable to find template "/myDocumentRoot/../app/var/files/5"</em></p>
  
  <p>I've also tried several relative paths without success. Any idea of how to achieve it?</p>
