We have a standard Wordpress installation being used as a CMS. We're using standard pages with basic permalinks (e.g., /page/ or /parent/page/).
We'd like to have that exact same content mapped to a virtual subdirectory as well (e.g., /vip/page/ or /vip/parent/page/).
Now, obviously, I could duplicate the pages in Wordpress, but that's too much of a pain to manage. The content in both versions would be identical, but we'd do a few minor things in the Wordpress template to display things slightly differently based on the detected URL.
I'm fairly certain there should be a way to do this using .htaccess, but I can't find the right combination of Google keywords to find my answer. Can someone point me in the right direction?
EDIT: It's also worth noting that I'm aware of the potential penalties for SEO, but I plan on supplying canonical meta tags for Google's purposes. The separate URL system is predominantly for marketing and tracking purposes only.
