I am currently running a wordpress multisite network on version 3.2.1. When the network was originally setup, it was marked as being for subdomains. This worked fine for simple domain mappings. However, a new scenario has come up that is a bit more complicated.
I have a client with 3 blogs hosted at another website in the format of;
mainblog.otherprovider.com
main.otherprovider.com/anotherblog
main.otherprovider.com/andanother
They currently have those blogs mapped to their primary domain in the same fashion;
blog.domain.com
blog.domain.com/anotherblog
blog.domain.com/andanother
What I'd like to do with multisite is setup those 3 blogs just like the other provider. This way the domain mapper plugin can map the site to their main blog subdomain, they can change their A records, and the move is all done. To do this, I would need to setup multisite as such;
blog.mywordpress.com
blog.mywordpress.com/anotherblog
blog.mywordpress.com/andanother
Unfortunately, I can't find any way of doing this in multisite. Each blog should be fully independent, but two should be hanging off subdirectories of the other.
