Part of what I was going to ask is answered here already. Including it for the on topic reference.
Without creating a new Portal, we have a single DNN instance, and we have 25+ pages. However, we want 3 of those pages to use a different domain (PortalAlias).
Is there some way to use the fields in TabUrls and/or their related settings, so that my target 3 pages sort of appear as a separate site from the outside?
It seems like it could or should be possible and would have something to do with the TabUrls fields PortalAliasId and PortalAliasUsage, but I have played around and can't seem to get it to work.
Has anyone else tried this and gotten it to work?
