Question

Is there a way to determine if the request is using HTTPS in node.js with express? I’m using Heroku with their certs which I’m assuming are installed at the load balancer and not on individual web servers/ instances.

Answer 1

If you can configure nginx, add this parameter in nginx config

proxy_set_header X-Forwarded-Proto https;

And then in your code check for it and set flag for other handlers.

mainapp.use(function(req, res) {

  if ( req.header('X-Forwaded-Proto') == 'https' ) {
     req.is_ssl = true;
  }
});
