Based on what I read above I got a simple solution that works on any browser:

1) on you logout page you call an ajax to your login back end. Your login back end must accept logout user. Once the back end accept, the browser clear the current user and assumes the "logout" user.

$.ajax({
    async: false,
    url: 'http://your_login_backend',
    type: 'GET',
    username: 'logout'
});      

setTimeout(function () {
    window.location.href = 'http://normal_index';
}, 200);

2) Now when the user got back to the normal index file it will try to automatic enter in the system with the user "logout", on this second time you must block it by reply with 401 to invoke the login/password dialog.

3) There are many ways to do that, I created two login back ends, one that accepts the logout user and one that doesn't. My normal login page use the one that doesn't accept, my logout page use the one that accepts it.
