Trying to segregate subdomain

EDIT I’ve moved this to the R7 forum

I’ll try to lay this one out as best I can.

I have a web server that hosts a single domain - domain.com, for example. This site hosts a single website. I’ve recently added another site at subm.domain.com. At the end of the day I’d like to be able to separate these two sites so that they have their own sitemaps. What is the best way to go about this? I’ve tried to fool google analytics by using URL redirections for the sitemap. This worked fine for the first site (domain.com/sitemap was redirected to the sitemap I had created in the database) but this isn’t going so well for the second db.

Is there a better way to do this? I had thought about using Internet Site docs but couldn’t tell from the help documentation if this was the way to go.
