  * DesktopEncoderRedirect Valve
 31   
  *
 32   
  * if request parameter encoder=desktop is NOT defined,
 33   
  *    redirect to same url with /desktop pipeline,
 34   
  * otherwise,
 35   
  *    just invoke next valve
 36   
  *
 37   
  * Used by the /render pipeline (desktop-render-pipeline) to allow
 38   
  * render requests that are not initiated via desktop javascript code to result
 39   
  * in a page level navigation to the /desktop pipeline with the correct portlet rendering
 40   
  * indicated in the original url. The encoder=desktop request parameter
 41   
  * is used by desktop javascript code to indicate that the request is an "official"
 42   
  * desktop ajax request.
