title: display a gif while asp.net page loads
body: <p>I have a lenghty ASP.NET page load process.</p>
  
  <p>Is there a way to display a loading gif while the ASP.NET page loads?</p>
  
  <p>Obviously I can't use an image on the page itself, and when I fiirst load a "dummy page" with the "Loading..." picture, that page is discarded as soon as I redirect the user to the real page...</p>
  
  <p>Any clue? Thanks</p>
