I'm taking part in a custom shared hosting solution, and we need help with a solution for DNS or routing. Right now, a user domain points to their share, but it must have the secondary name in it.
What is the best way for us to point user.domain.com to user.secondary.domain.com?
The redirect needs to work for http/ftp/ssh.
Simply put, we have a master server then slave servers, we want each user to have their own domain/subdomain. CNAME is the obvious answer, but is it the only solution, since if we have a lot of clients that will make A LOT of DNS records on our DNS server.
