I have a server with a subdomain -, and we have a client that wants to map one of their subdomains to ours.

We are running centos.

My understanding is that the client has to create a cname record that points from their subdomain to

However, I am not sure if I need to actually do anything on my side to enable this?

They need to create a CNAME that points to (without any http or anything).

If you run Apache on your server, you then need to add an ServerAlias with the domain name of your client to the vhost that should handle these requests.

Beaware that it won't like doing this with https, as certificates only work for a single domain. – AliGibbs Mar 28 '12 at 13:30
OK, this need to work with SSL - what needs to happen in this case? – JonoB Mar 28 '12 at 13:41
Server Name Indication works for newer clients. If you have older clients (such as IE 6) and you care about the warning they get then you will need another IP address. – Ladadadada Mar 28 '12 at 13:56
