Node HTTP to HTTPS

'use strict';

// Firstly, please don't use this in production.
// Use nginx forwarding/upstream instead
// Nginx is way more secure and battle-tested

// ### Method 1 ###

// Detect the protocol (HTTP or HTTPS)
// if HTTPS, continue...
var schema = (req.headers['x-forwarded-proto'] || '').toLowerCase();
if (schema === 'https') {
	next();
} else {
	// Redirect or Deny request
	// Example: res.redirect('https://yoursite.com');
}

// ### Method 2 ###
// ################

// Regular HTTP server
var http = express.createServer();

// Redirect all traffic to HTTPS
http.get('*', function (req, res) {
    res.redirect('https://' + req.headers.host + req.url);
}).listen(8080);

// Add these Firewall Rules
// iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080
