code: public Action getAction(String url, String[] urlPara) {
  		Action action = mapping.get(url);
  		if (action != null) {
  			return action;

  		// --------
  		int i = url.lastIndexOf('/');

docs: Support four types of url
  1: http://abc.com/controllerKey                 ---> 00
  2: http://abc.com/controllerKey/para            ---> 01
  3: http://abc.com/controllerKey/method          ---> 10
  4: http://abc.com/controllerKey/method/para     ---> 11
  The controllerKey can also contains "/"
