/* 

      This server-side JavaScript library implements a class named "CGIVariables" which allows for easy access 

      to most CGI variables in XPages via JavaScript. 

      For example, to dump the remote users name, IP address and browser string to the server console, use: 

      var cgi = new CGIVariables(); 

      print ("Username: " + cgi.REMOTE_USER); 

      print ("Address : " + cgi.REMOTE_ADDR); 

      print ("Browser : " + cgi.HTTP_USER_AGENT);
