 23:  * Media View provides a custom view implementation for sending files to visitors. Its great
 24:  * for making the response of a controller action be a file that is saved somewhere on the filesystem.
 25:  *
 26:  * An example use comes from the CakePHP internals. MediaView is used to serve plugin and theme assets,
 27:  * as they are not normally accessible from an application's webroot. Unlike other views, MediaView
 28:  * uses several viewVars that have special meaning:
 29:  *
 30:  * - `id` The filename on the server's filesystem, including extension.
 31:  * - `name` The filename that will be sent to the user, specified without the extension.
 32:  * - `download` Set to true to set a `Content-Disposition` header. This is ideal for file downloads.
 33:  * - `path` The absolute path, including the trailing / on the server's filesystem to `id`.
 34:  * - `mimeType` The mime type of the file if CakeResponse doesn't know about it.
 35:  *  Must be an associative array with extension as key and mime type as value eg. array('ini' => 'text/plain')
 36:  *
 37:  * ### Usage
 38:  *
 39:  * {{{
 40:  * class ExampleController extends AppController {
 41:  *      public function download() {
 42:  *          $this->viewClass = 'Media';
 43:  *          $params = array(
 44:  *              'id' => 'example.zip',
 45:  *              'name' => 'example',
 46:  *              'download' => true,
 47:  *              'extension' => 'zip',
 48:  *              'path' => APP . 'files' . DS
 49:  *          );
 50:  *          $this->set($params);
 51:  *      }
 52:  * }
 53:  * }}}
 54:  *
 55:  * @package       Cake.View
 56:  * @deprecated Deprecated since version 2.3, use CakeResponse::file() instead
