     *   If path is set to '/foo/', the cookie will only be available within the
     *   /foo/ directory and all sub-directories such as /foo/bar/ of domain.
     *   The default value is base path of app. For e.g. if your app is running
     *   under a subfolder "cakeapp" of document root the path would be "/cakeapp/"
     *   else it would be "/".
     * - `domain` - The domain that the cookie is available. To make the cookie
     *   available on all subdomains of example.com set domain to '.example.com'.
     * - `secure` - Indicates that the cookie should only be transmitted over a
     *   secure HTTPS connection. When set to true, the cookie will only be set if
     *   a secure connection exists.
     * - `key` - Encryption key used when encrypted cookies are enabled. Defaults to Security.salt.
     * - `httpOnly` - Set to true to make HTTP only cookies. Cookies that are HTTP only
     *   are not accessible in JavaScript. Default false.
     * - `encryption` - Type of encryption to use. Defaults to 'aes'.
