问题：
A Company.com developer has created a web application that includes a servlet for each use case in the application.

There is also common processing code in many servlets because these use cases are very similar.
Which two design patterns can be used together to refactor and simplify this web application？ （）
A . Proxy
B . View Helper
C . Front Controller
D . Session Façade
E . Business Delegate
F . Model-View-Controller
