Interface for applications that use routing.
Class for generating asset URLs.
Provides features for building routes inside scopes.
Contains a collection of routes.
Parses the request URL into controller, action, and parameters. Uses the connected routes to match the incoming URL string to parameters that will allow the request to be dispatched. Also handles converting parameter lists into URL strings, using the connected routes. Routing allows you to decouple the way the world interacts with your application (URLs) and the implementation (controllers and actions).
