I'd like my FB canvas app
apps.facebook.com/coolapp
to behave the same as my web app
coolapp.com
I've set up the canvas url in facebook developer page
http://coolapp.com/canvas/
Using Rails 3.1, I'd like to know how I can easily route the /canvas into my app so that going to the first url above does not route outside of the facebook canvas page (and all the resources work as expected).
