We have a Rails 3 app which allows users to create a profile and access it with a subdomain. So for example:
- user1.app.com
- user2.app.com
- user3.app.com
Now, suppose they wanted to point their own domain name to their profile, so www.user1.com shows user1.app.com, and www.user1.com/my-content/ shows user1.app.com/my-content/. Is it possible for them to simply change their nameservers to point to us, and we handle the routing? I'm afraid it would be a deal breaker if the user had to do any DNS configuration beyond just changing their nameservers.
Thanks!
