Area-global filters in MVC 3

Since it doesn't appear to be support开发者_StackOverflow社区ed natively, what's the recommended way of implementing global filters on a per-area basis?

---

The reason it's not supported natively is because we want to discourage developers from doing it. Areas are not associated with controllers; they're associated with routes. We wanted to discourage developers from trying to apply authorization or other security-sensitive filters to areas since they can be bypassed.

See How can we set authorization for a whole area in ASP.NET MVC? for more information.

You could use a custom IFilterProvider.
