How I log out

[Doppy]

Anyone can suggest me how I can log out in the forum? what code or what file.js can I wacth to create a log out ?

For now I do this:

(library.js)

router.get('/client/pagina-utente-cancellato',hostMiddleware.buildHeader,controllers.caricaPaginaUtenteCancellato);

(controllers.js)

Controllers.caricaPaginaUtenteCancellato=function(req,res,callback){
	//delete req.session;
	//console.log(req);
	req.logout();
	
	res.render('client/pagina-utente-cancellato', {});
};

Buw when I go in /client/pagina-utente-cancellato I must reload to see that the user is
not logged. I need that in the header I can see "register" and "login" and not the value of current logged user. Anyone can help me?
