There is nothing about server-side that makes it stateless. The
interaction between client and server is what is stateless, thus
things are stateless from the perspective of the client as well (it
must maintain state itself).

You're looking at cookies or sessions. Either set the cookie directly
via JS, or use a trick like:

var a = 1;
(new Image()).src = '/myscript.php?a='+ a;

Then myscript.php can set the cookie or use session.
