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).** ### Connecting routes** Connecting routes is done using Router::connect(). When parsing incoming requests or reverse matching* parameters, routes are enumerated in the order they were connected. You can modify the order of connected* routes using Router::promote(). For more information on routes and how to connect them see Router::connect().** ### Named parameters** Named parameters allow you to embed key:value pairs into path segments.

This destination is expressed as an associative array by Router. See the output of {@link parse()}.** $options offers four 'special' keys. `pass`, `named`, `persist` and `routeClass`* have special meaning in the $options array.** - `pass` is used to define which of the routed parameters should be shifted into the pass array. Adding a* parameter to pass will remove it from the regular route array. Ex. `'pass' => array('slug')`* - `persist` is used to define which route parameters should be automatically included when generating* new URLs. You can override persistent parameters by redefining them in a URL or remove them by* setting the parameter to `false`. Ex. `'persist' => array('lang')`* - `routeClass` is used to extend and change how individual routes parse requests and handle reverse routing,* via a custom routing class. Ex. `'routeClass' => 'SlugRoute'`* - `named` is used to configure named parameters at the route level. This key uses the same options* as Router::connectNamed()** You can also add additional conditions for matching routes to the $defaults array.* The following conditions can be used:** - `[type]` Only match requests for specific content types.* - `[method]` Only match requests with specific HTTP verbs.* - `[server]` Only match when $_SERVER['SERVER_NAME'] matches the given value.** Example of using the `[method]` condition:** `Router::connect('/tasks', array('controller' => 'tasks', 'action' => 'index', '[method]' => 'GET'));`** The above route will only be matched for GET requests.
