        Here's a short reminder on what elements you have at your disposal:
  
negative.code:     String pageurl = wiki.encodeName( pagereq );
  
      String action = request.getParameter("action");
      String ok = request.getParameter("ok");
      String preview = request.getParameter("preview");
  
      //
      //  Set the response type before we branch.
