title: Cname redirect to heroku?
body: <p>I have an application on Heroku. I cname-redirect <a href="https://login.zenconomy.se" rel="nofollow">https://login.zenconomy.se</a> to <a href="https://boomeranglogin.herokuapp.com/" rel="nofollow">https://boomeranglogin.herokuapp.com/</a></p>
  
  <p>I get the following (yellow) error in chrome:</p>
  
  <p>This is probably not the site you are looking for!
  You attempted to reach login.zenconomy.se, but instead you actually reached a server identifying itself as *.herokuapp.com. This may be caused by a misconfiguration on the server or by something more serious. An attacker on your network could be trying to get you to visit a fake (and potentially harmful) version of login.zenconomy.se.
  You should not proceed, especially if you have never seen this warning before for this site.</p>
  
  <p>Why?</p>
