I've got a domain hosted (DNS only) on Dreamhost. I've got www.mydomain.com CNAME'd to my web app on heroku, I would also like to CNAME just the domain (mydomain.com). Ofcourse, you can only CNAME subdomains. 

What should I do to make mydomain.com point to my heroku app, or even redirect to www.mydomain.com?

Cheers!
