title: FormsAuthentication RedirectToLoginPage Quirk
body: <p>Using this method after the SignOut() call redirects to '...login.aspx?ReturnUrl=%2fmydomainname%2flogout.aspx' so that the user can't log back in again, since a successful login returns to the logout page. The login page is set in webconfig and the app successfully gets that page. Why would a ReturnURL be stuck on the tail of the URL?</p>
