Running apps on heroku in 'http' instead of 'https'

I have deployed the demo app of Michael Hartl's tutorial code onto heroku to see its working. The app opens in https://some-app-name.herokuapp.com. How do i get it to open in http rather than https?

Does Heroku use https by default?

herokuapp.com SSL certificate. No special configuration is needed, just access the app with https and you're secure by default.

Does Heroku require SSL?

While it has been communicated previously and documented in multiple places, SSL requirements for client connections have been loosely enforced on the Common Runtime platform.

Had the same problem. You have to change ssl settings for your app.

In environments/production.rb there must be following configuration config.force_ssl = false which by default is set to true.

Had to reset Firefox to take effect. Other browsers were ok.
