Node application: Http to Https redirection does not work for localhost

I am adding HTTPS to a node.js application, while forwarding HTTP to HTTPS. I am using the following bit of code:

    // Trusting proxy
    self.app.enable('trust proxy');

    // Http -> Https redirection middleware
    self.app.use(function (req, res, next) {

        var schema = req.protocol.toLowerCase();
        console.log("Redirection check, schema: " + schema);

        if (schema === 'https') {
            console.log("Next");
            next();
        } else {
            var tmp = 'https://' + req.headers.host + req.url;
            console.log("Redirect to: " + tmp);
            res.redirect(tmp);
        }

    });

All works fine when I browse https://localhost:8443/index.html, the page opens fine.

But when I try http://localhost:8443/index.html, Chrome seems to redirect or rewrite the url to localhost:8443/index.html and Chrome waits for localhost eternally. There is no console message from my application. I am on under windows 7 with Chrome.

What is wrong with my code?
