[WP Multisite] Same cache for all?

@esiinformatique Yes we all have the same problem by the way I fixed it this way:
in folder : plugins/cache-master/vendor/shieldon/simple-cache/src/SimpleCache/Driver
depend on which driver we use example I’m using redis so open Redis.php in the last line we have a function:

    private function getKeyName(string $key): string
    {
        return 'sc:' . $key;
    }

By replace it this :

    private function getKeyName(string $key): string
    {
        $prefix = 'sc_'.$_SERVER['SERVER_NAME'].'_';
        return $prefix . $key;
    }

Did anyone figure out how to fix this? It was going so well until I discovered this problem. I’ve got Memcache and Wincache and they both do it.
