/**

 * 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).

 *

 * ### 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 allows you create hash

 * structures using URLs. You can define how named parameters work in your application using Router::connectNamed()

/**

 * Connects a new Route in the router.

 *

 * Routes are a way of connecting request URLs to objects in your application. At their core routes

 * are a set of regular expressions that are used to match requests to destinations.

 *

 * Examples:

 *

 * `Router::connect('/:controller/:action/*');`

 *

 * The first token ':controller' will be used as a controller name while the second is used as the action name.

 * the '/*' syntax makes this route greedy in that it will match requests like `/posts/index` as well as requests

 * like `/posts/edit/1/foo/bar`.

 *

 * `Router::connect('/home-page', array('controller' => 'pages', 'action' => 'display', 'home'));`

 *

 * The above shows the use of route parameter defaults, and providing routing parameters for a static route.

 *

 * ```

 * Router::connect(

 *   '/:lang/:controller/:action/:id',

 *   array(),

 *   array('id' => '[0-9]+', 'lang' => '[a-z]{3}')

 * );

 * ```

 *

 * Shows connecting a route with custom route parameters as well as providing patterns for those parameters.

 * Patterns for routing parameters do not need capturing groups, as one will be added for each route params.

 *

 * $defaults is merged with the results of parsing the request URL to form the final routing destination and its

 * parameters. 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. POST requests will fail to match this route.

 *

 * @param string $route A string describing the template of the route

 * @param array $defaults An array describing the default route parameters. These parameters will be used by default

 *   and can supply routing parameters that are not dynamic. See above.

 * @param array $options An array matching the named elements in the route to regular expressions which that

 *   element should match. Also contains additional parameters such as which routed parameters should be

 *   shifted into the passed arguments, supplying patterns for routing parameters and supplying the name of a

 *   custom routing class.

 * @see routes

 * @see parse().

 *

 * Examples:

 *

 * `Router::redirect('/home/*', array('controller' => 'posts', 'action' => 'view'), array('persist' => true));`

 *

 * Redirects /home/* to /posts/view and passes the parameters to /posts/view. Using an array as the

 *

 * `Router::redirect('/posts/*', 'http://google.com', array('status' => 302));`

 * Do not parse any named parameters:

 *

 * ``` Router::connectNamed(false); ```

 *

 * Parse only default parameters used for CakePHP's pagination:

 *

 * ``` Router::connectNamed(false, array('default' => true)); ```

 * Parse only the page parameter no matter what.
