How does VKontakte change the url without reloading the page?

Question

JavaScript

Vkontakte, when you click on the links, the url changes (not the hash, but the url itself). At the same time, the page does not reload (for example, the player, if it is running, continues to play wherever we go).

Can someone explain how this magic is done?
Thanks

Answer 2

This does not work in all browsers.
javascript:history.pushState({}, '', '/page/');

Answer 3

I don’t sit on vkontakte, but I can assume that tricky js + ajax is used.
