title: How can I tell if a request is made with AJAX in Kohana 3?
body: <p>I've tried these</p>
  
  <pre><code>request::is_ajax()
  
  Request::instance()-&gt;is_ajax
  </code></pre>
  
  <p>To no avail. I've noticed in the <code>request</code> class there is a public property <code>$is_ajax</code> but I can't seem to be able to access the property.</p>
  
  <p>What am I doing wrong?</p>
