Answer
Filters run at specific pipeline stages: Authorization, Resource, Action, Exception, and Result filters. They implement cross-cutting concerns like logging, caching, or auditing.
Quick Answer
Filters are pipeline hooks for cross-cutting concerns. Authorization Filters run first and can short-circuit unauthenticated requests. Action Filters run before/after the action — log parameters, validate headers. Result Filters wrap result execution — modify output. Exception Filters handle unhandled exceptions from actions. All can be scoped globally, per-controller, or per-action.
