title: wrong $_GET request
body: <p>I have a URL: </p>
  
  <pre><code>http://missk.co.uk/index.php/admin/catalog_category/index/key/a47a4f77942acca6e40cdca9736d2a3d/
  
  var_export($_GET) :
  
  array ( '/index_php/admin/catalog_category/index/key/a47a4f77942acca6e40cdca9736d2a3d/' =&gt; '', )
  </code></pre>
  
  <p>Why I receive not the empty array though $ _GET has to give out parameters only after a question mark?</p>
