Trying to ask a question for the second time. Repost to get seen.

I need the domain mapper to work like this...

If you go to HollyLovett.com it goes to HollyLovett.com (in the url). If you go to MainStreetAgents.com/holly-lovett, it goes to MainStreetAgents.com/holly-lovett (in the url).

This is extremely important as it's a fundamental feature to the free wordpress.com domain mapper.

There are check boxes to leave the admin url or map it. Please tell me what snippet I can add to make the mapper work this way.

Without this functionality, a subdirectory WP multisite can't get around SSL certificates.
