[xwiki-users] Using 2 different SSL certs for 2 different xwiki's on 1 server

Up until the point, we've had only 1 wildcard SSL cert for our site because we've only had one domain we were using, say example.com. But we've just added a wiki to our farm which is going to be using a different domain, say newdomain.org. We've obtained the certs for them, but I don't know where or how to configure apache/ssl to recognize the certs for the new wiki. I assume it's in the ssh.conf file. Has anyone done this successfully? Sam
