[support] multisite +OG +CNAME

[Miles Fidelman]

Hi Folks,

Question from a newbie getting ready to set up a new Drupal installation.

I was wondering if it's possible, and if so, how, vector a domain name 
to an organic group.

E.g.,

www.foo.org CNAME foo.oursite.org

www.oursite.org is a server running multiple drupal sites

foo.oursite.org is a virtual site running at the same IP address as 
www.oursite.org

when someone tries to go to www.foo.org, we'd like them to end up in an 
organic group, within foo.oursite.org

---
I assume that I set up a site folder for foo.oursite.org within the 
www.oursite.org tree.

Since the user will be entering URLs of the form www.foo.org/... - do I 
need to have an alias defined so that the foo.oursite.org folder also 
has the name www.foo.org?

What do I need to do to get users vectored to an organic group defined 
within foo.oursite.org?

Thanks very much,

Miles
