I have installed OOD 3.0 and set up hostname profile selection.

In order to get the same OOD portal running under two names, my plan is to copy the apache config and find/replace the ServerName as well as the certificate/private key locations. But I get the feeling that there is a better way. Ideally this could be done in my ood\_portal.yml. Is that possible?

> 3.0 supports server aliases, looks like we just forgot to document it. I don’t think I follow number 2, but I see that we do force the value instead of overwriting it. @tdockendorf do you know more about why this may be an issue for HAPorxy environments?
