     * Devuelve un array con todos los valores 
     * de la variable superglobal $_SERVER
     * NOTA: filter_input para las opciones INPUT_SERVER y 
     * INPUT_ENV no funcionan para FASTCGI
     *
     * @return array
     */
    public static function getAllValues( )
    {
        $ret = [ ];
        foreach ( array_keys( $_SERVER ) as $key) {
            $exists = filter_has_var( INPUT_SERVER, $key );
            if ($exists) {
                $value = filter_input( INPUT_SERVER, $key );
            } else {
                $value = filter_var( $_SERVER[ $key ], 
                                     FILTER_DEFAULT, 
                                     null );
            }
            $ret[ $key ] = $value;
        }

        return $ret;
