Redirect URLs within the Lithium framework via simple routes.

li3-RedirectsController.php

<?php

namespace app\controllers;

/**
 * Redirects Controller | This controller is designed to work in conjunction
 * with `routes.php` by routing the desired URL to a new one. E.g.,
 * redirecting '/keepinitreal' to the static directory '/mycard/loyalty-card'.
 * 
 * ```php
 * Router::connect('/keepinitreal', array('Redirects::index', 'args' => array('/mycard/loyalty-card')));
 * ```
 * 
 * In the case of permanent 301 redirects (e.g., changing the URL of '/grow-
 * us' to '/franchise') the `.htaccess` file ought to be utilized instead. It
 * will be a) faster and b) recognized by search engines.
 * 
 * Note: The redirect destination *should* be an absolute URL. A relative URL
 * will work, but absolute is best practice.
 *
 * ```
 * # Change URL of '/grow-us' page to '/franchise'
 * Redirect 301 /grow-us http://yeahburger.com/franchise
 * ```
