Force my heroku app to use SSL (https)
<p>I have a node app running successfully on Heroku. I have purchased an Expedited SSL certificate and it all works fine. I go to https... and get a full 'green bar' proving the site is being served over https</p>

<p>However, the non-SSL standard http is still available too. How can I force the app to serve over https? Thanks</p>
