Cookie stored in server as well as client?

Hi, In the Flashcards project (techdegree unit 6), when a POST request is received a cookie is "created" by Express and sent back to the client using the res.cookie() method:

router.post('/hello', (req, res) => {
  res.cookie('username', req.body.username);
  res.redirect('/');
});

And also immediately redirects to the / route, which is:

router.get('/', (req, res) => {
    const name = req.cookies.username;
    if (name) {
      res.render('index', { name });
    } else {
      res.redirect('/hello');
    }
});

So my first question is, does the /hello route a) redirect the CLIENT to the / route, or b) does it redirect itself straight to the / route, which then causes the 'index' template to be rendered (assuming if (name) === true)?

Second question is: if a) happens above then I guess the / route has received a new GET request from the client so the cookie is available, but if b) above is true, how would the / route have access to the coookie? (Unless is it also 'stored' on the server?)

Thanks you !!!
