URL redirecting

I am working on a FTP server on which the IP address could be changed under admin privileges. After the IP is change I perform a customizeReset(). How could a redirect the clients to the new URL location after reset?

Can you send a message to the clients telling them that the URL is changed - that they would understand?

That’s what I am doing as for now. But I was hoping there was a way of redirecting without having to do any notification. Could that be accomplished using the RpSetRedirect routine ?
