For a simple setup where the user/client app accesses MinIO directly (i.e. with no intervening proxies/load-balancers), and each MinIO server (if there are more than one) has a unique domain name, this redirection should work automatically with no further configuration. For example, if the MinIO service is being accessed by the browser at the URL `https...
