Asp.net MVC page life cycle

What is the best way to apply a treatment after the page is rendered (v开发者_如何学Goiew calculated, html helpers calculated, partial views calculated and so on...) but before the response is sent to the client ? In order to modify this response (with DB access needed)...

Thank you
