Pointoing my Heroku Rails app to www and without www works only for an hour?
===

My Rails app works with Heroku and if I set my CNAME at my domain register Afrihost to www.domain and without the www it works fine for an hour. Then it kills the app without the www domain infront and I have to log in and change the dns again.

Afrihosts states, because of a certain law it can't point a cname to both with a www and without a www in-front. Is that true for all domain registers?

What alternatives are there as I want to point to both with and without the www in-front.

Thanks in advance.
