Correct Event to check user authentication in BaseController class
===

I'm in the process of converting a web application of mine to an MVC application. I think it will benefit from it but I'm a newb and a half at MVC. I want all of my controllers to inherent from a base controller and the first thing I want to do is redirect the User to the Login view if they are not authenticated. The method already written basically looks for a Cookie and if it doesn't find it does a Response.Redirect() to the login screen. I want to move this method to the BaseController but I'm not positive what's the best way to go about it. So in essence what BaseController Event should I invoke to check for authentication before loading the page?

Thanks
