Redirect a Rails app on Heroku

Question

I'm hosting a Rails app on Heroku, using the Zerigo DNS. I've added both www.mydomain.com and http://mydomain.com.

My question is this: what is the best way to add a redirect so that http://mydomain.com redirects to www.mydomain.com? Would it be better to add the redirect on Zerigo? Or write some code in Rails to do the redirecting?

Any thoughts are much appreciated.

Answer 1

using DNS, just point your root domain to redirect to the www. subdomain.

Answer 2

Add a CNAME record with www host and simply point it to your http://whateverapp.heroku.com

It works for me perfectly!
