Question

What I need to do is execute some code before the MVC executes the controller and after it finishes generating the View.
Is there any way to do this?

I need to integrate the MVC application with an existing cache system, so:

• before executing the controller, instantiate a cache.
• after the view was generated, destroy the cache.

Action Filter Attributes enable you to inject code interceptors into the request of a MVC controller that can execute before and after a Controller or its Action methods execute.
