* @param string $key The key under which to store the value.
* @param string $group The group value appended to the $key.
* @param int $time The amount of time the server will wait to delete the item in seconds.
* @param string $server_key The key identifying the server to store the value on.
* @param bool $byKey True to store in internal cache by key; false to not store by key
