What is the difference between FilterDispatcher and ActionServlet?

The controller in Struts1.x is the ActionServlet which is a Front Controller, which does not give the guarantee for trapping the response but the controller should trap both the request and response thus Struts2.x uses FilterDispatcher which is a predefined Filter so there is a guarantee of trapping the response also.
