FormsAuthentication.RedirectToLoginPage() does nothing

Question

I have the following problem: republishing ASP.NET web app causes (as expected) session resetting where I keep additional user info (what on access attempt will cause NullReferenceException).

To avoid that, my page checks this info existence and in case of null redirects user to the login page (forms auth), so I'm calling:

void LogOut()
{
    Session.Clear();
    Session.Abandon();
    User = null;
    FormsAuthentication.SignOut();
    FormsAuthentication.RedirectToLoginPage()
}

But sometimes it doesn't help, so I found a workaround:

Response.Redirect(FormsAuthentication.LoginUrl);

but it doesn't add returnUrl, what I wish it were (I don't want to emulate this behavior manually).

So want to figure out why does the first way doesn't work as expected.

Have you tried calling Response.End() after FormsAuthentication.RedirectToLoginPage() ?
