Cannonbose recently released CB RealURL to automate the realURL configuration process. I just tested cbrealurl with realurl version 1.2.1 and had everything up and running in a couple minutes!

Don't forget to Include CB RealURL in static (from extensions):

Also make sure you uncomment and configure your base config.baseURL if you haven't done so already
