Answer 1

The usual reasons you see multiple requests when a page loads from a browser are one of two things:

1. The browser automatically requesting the favicon.ico file.
2. The browser attempting to load some resource from the HTML file (script file, image, CSS file, etc..)

You can see exactly what each request is for by adding:

console.log(req.url);

to your middleware.
