Corsware is a by-the-book and feature complete implementation of the CORS Specification for Iron. Corsware supports many features, including authentication, preflight request detection, normal request decoration, allowing credentials, origins, methods and headers, exposing headers, handling null Origins and setting Max-Age.
The middleware itself is simply a standard Iron AroundMiddleware and contains no special routing logic.
