A URI decorator in OpenRasta is a class that lets you manipulate URIs before a request is processed. They are used for implementing various features, such as content negotiation via file extensions, localized URIs, and whatever else you may think of (implement IUriDecorator to make your own).

Register a UriDecorator with OpenRasta using the ResourceSpace.Uses construct.
