Does it have to be in Rails? This is pretty easy to do with Apache, for instance.

Answer 2

Sometimes your host won't let you do redirects, so I think it's ok practice to do it either in your application_controller or middleware. If you're on Rails3, check out this no-www gem

This SO Question has examples of going from www to no-www and from no-www to www.
