         Here's a short reminder on what elements you have at your disposal:
  
positive.code: 
      log.debug("Request character encoding="+request.getCharacterEncoding());
      log.debug("Request content type+"+request.getContentType());
  
      if( action != null && action.equals("save") )
      {
          log.info("Saving page "+pagereq+". User="+request.getRemoteUser()+", host="+request.getRemoteHost() );
  
  
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.
