I've been researching this for awhile now, but I can't find an answer. I'm using the domain mapping plugin, and I'm trying to figure out how to do domain mapping when my MU install is itself an addon domain. For example:
My MU install is located at public_html/mysite.com
I've added an addon domain which is located at public_html/mysecondsite.com
Should I redirect mysecondsite.com to mysite.com? Or should I the addon domain document root to be the same as the MU installation?
Can someone please point me in the right direction?
