Make node.js express respect x-forwarded-proto on res.redirect

app.js

app.configure(function(){
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');


  // use this to let express know it is on a encrypted connection
  app.use(function(req, res, next) {
    var schema = req.headers["x-forwarded-proto"];

    if (schema === "https") {
      req.connection.encrypted = true;
    }

    next();
  });

  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(app.router);
  app.use(express.static(__dirname + '/public'));
});

Awesome!
