title: Show preloader only once per session
body: <p>Ive been trying some answers on similiar questions but I've not managed to get it to work. I've got the script below witch shows a preloader on the homepage everytime, and I want only to show once per session or the cache is cleared. </p>
  
  <p>Any Help will be much appreciated!       </p>
  
  <pre><code>jQuery(window).load(function() {
    jQuery("#status").delay(2000).fadeOut("slow");
    jQuery("#preloader").delay(2500).fadeOut("slow");
  });
  </code></pre>
