FiltersReminder.txt

The ASP.NET MVC framework supports four different types of filters:

    Authorization – Implements  IAuthorizationFilter Attribute.
    Action        – Implements IActionFilter Attribute.
    Result        – Implements  IResultFilter Attribute.
    Exception     – Implements  IExceptionFilter Attribute.
    
Note: Filters are executed in the order listed above. 
Authorization filters run very early in the action pipeline. 
They are good for example to escape from the action pipeline when conditions are not met.
