I am trying to map my (naked) domain to an app.
I found this:
I'd like to map my app to http://myurl.com (also known as a naked domain). Due to recent changes, Google App Engine no longer supports mapping your app to a naked domain. If your domain registrar supports URL redirects, you can redirect from http://yourdomain.com to your app, which can be served from domains like http://www.yourdomain.com or http://appid.yourdomain.com. For instructions on how to configure a redirect for your Google Apps domain, please see the article on URL forwarding.
I'd like not to resort to redirection. I understand udacity.com is hosted on appengine and they seem to use a naked domain.
So, I'm hoping this is just typical bad documentation or not updated. Does anybody have any info on how Udacity solves this problem or how could I produce such a behaviour ?
