Heroku still responds to mysubdomain.herokuapp.com

I have added a custom domain to my Heroku application and it works fine, but the application still responds to {mysubdomain}.herokuapp.com.

To prevent duplicate content I would like to stop having my application respond to the subdomain. Is there some setting in Heroku which does this for me, or do I need to code a 301 redirect?

I created the hide_heroku gem to handle this- it uses X-Robots-Tag HTTP headers to prevent search engines from indexing anything under *.herokuapp.com

Another option is to use the rel="canonical" link tag. This tells search engines which URL to use for content that may appear on multiple URLs:

<link rel="canonical" href="http://www.example.com/correct_url">

Here's what google has to say: http://support.google.com/webmasters/bin/answer.py?hl=en&answer=139394

(Your use case is explicitly mentioned at the bottom.)

I don't believe it's possible to remove the Heroku-provided domain name, either via their web interface or the command-line client. If you're concerned about it, redirect or add a robots.txt to your site that blocks when accessed via .herokuapp.com (I don't know how to do that offhand, sorry).

I suspect Google is reasonably smart about indexing Heroku sites and handles the dual-domain issue itself, but that's just a guess.

You would need a 301 redirect. Heroku will always respond to the .herokuapp.com domain of your app
