Intercept ASP.NET MVC 4 response generation

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.

Answer 1

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.

明显的答案是global.asax中的Application_BeginRequest和Application_EndRequest还是我缺少什么？

Answer 3

If you want to hook into page events, you'll probably want to implement your own WebViewPage and WebViewPage classes. Specifically, you'll want to decorate the Execute method. Phil Haack has a blog post on how to do this.
