Normal async XMLHttpRequest (including fetch) tend to be cancelled as the page closes. The usual workaround has been to make synchronous requests.

However, there's a new way to do it: navigator.sendBeacon. It was designed with pretty much that exact purpose in mind - it will queue a request to be executed even after the page is closed.

window.addEventListener("unload", function() {
  navigator.sendBeacon("/logout");
});

It still doesn't work on all browsers, so if you care about the lag-behinders you might want to test if it is available, and use the above-mentioned workaround if not.
