title: get parameters from $_SERVER['HTTP_REFERER']
body: <p>I want to get a value from the http_referer in the same/similar way you'd get it from a request:</p>
  
  <pre><code>$this-&gt;_getParam('order', 0);
  </code></pre>
  
  <p>I thought I'd try something like this:</p>
  
  <pre><code>$lastrequest = new Zend_Controller_Request_Http($_SERVER['HTTP_REFERER']);
  $lastorder = $lastrequest-&gt;getParam('order', 0);
  </code></pre>
  
  <p>But that doesn't work. There are no parameters. getParams returns an empty string. What am I missing? Is there a better way to do this?</p>
  
  <p>Thanks!</p>
