Let’s say you have site 1, site 1a, site 1b, and so on set
up on your server. You would like to
have an alias for site 1b that only site 1b can get you then it needs to be set
up under site 1b site folder. If you
want a link that all sites share then you will need to do it under the root
site, site 1. This will be called
default under the alias settings in the product. These rules apply to all manual alias and
automatic aliases.
