Answer 1

There are no redirects from a Javascript generated Ajax call which your $.post() is. Ajax sends a request, gets a response. An ajax call by itself does not change the page location at all. That's a characteristic of Ajax calls.

Redirects work when the browser is loading a new page and the server tells it to change what page it is loading to a new source, not when the browser just sends an Ajax call.

You can, of course, use your client-side Javascript to decide to redirect from the client side after your $.post() finishes. You could even have the response from the $.post() be the new location and your client-side Javascript could then just set window.location to that new URL.

function logOut() {
    $.post("/logout").then(function(data) {
        window.location = data.redirectUrl;
    });
}

And, on the server:

router.post("/logout", function (req, res) {
  req.logout();
  req.session.destroy();
  res.send({err: 0, redirectUrl: "/"});
});
