Redis cache with socket

Hello,

In Codeigniter 3, the Redis cache driver can connect via socket with this code :

PHP Code:

if ($config['socket_type'] === 'unix') {
    $success = $this->_redis->connect($config['socket']);
} else { // tcp socket
    $success = $this->_redis->connect($config['host'], $config['port'], $config['timeout']);
} 


I can be wrong, but it seems like it's no longer supported by the RedisHandler in Codeigniter 4. Any reason for that change ?

Thanks for your help !
