     *
     * - `cookie` - The name of the cookie to use. Defaults to value set for `session.name` php.ini config.
     *    Avoid using `.` in cookie names, as PHP will drop sessions from cookies with `.` in the name.
     * - `cookiePath` - The url path for which session cookie is set. Maps to the
     *   `session.cookie_path` php.ini config. Defaults to base path of app.
     * - `timeout` - The time in minutes a session can be 'idle'. If no request is received in
     *    this duration, the session will be expired and rotated. Pass 0 to disable idle timeout checks.
     * - `defaults` - The default configuration set to use as a basis for your session.
     *    There are four built-in options: php, cake, cache, database.
     * - `handler` - Can be used to enable a custom session handler. Expects an

     *    class to use for managing the session. CakePHP bundles the `CacheSession`
     *    and `DatabaseSession` engines.

     *
     * Within the `ini` key, you will likely want to define:
     *
     * - `session.cookie_lifetime` - The number of seconds that cookies are valid for. This
     *    should be longer than `Session.timeout`.
     * - `session.gc_maxlifetime` - The number of seconds after which a session is considered 'garbage'
     *    that can be deleted by PHP's session cleanup behavior. This value should be greater than both
     *    `Sesssion.timeout` and `session.cookie_lifetime`.

     * - 'database' - Uses CakePHP's database sessions.
     * - 'cache' - Use the Cache class to save sessions.
     *
