you should also provide a fully qualified url
My bad: I was cutting-and-pasting from MAMP (free version), where you can't put a full domain name in the target. Feel free to bring out the administratorial scissors ;)
i would suggest adding a condition to limit that RewriteRule from firing for lower case directory names.
Let's make that "You MUST add a condition" because otherwise you'll get an infinite redirect loop. (It didn't happen to me only because of the particular way I set up my experiments, or I would speedily have noticed!*)
* What I did notice was that MAMP includes mod_speling, so WrOnG CasE directory names still resolve. Luckily it doesn't happen on my live site. Can you spell "duplicate content"?
