title: ssl on custom domain for heroku app
body: <p>I want to connect a custom domain to an app built on Heroku. Can someone confirm that I actually need to buy a certificate and in addition buy the SSL addon on Heroku?</p>
  
  <p>Do I need both or is one of them enough? What is the point of the addon?</p>
