Cannot log off while using asp.net mvc5 identity, cookies refreshed on posting

Question

I'm working on asp.net MVC5 with VS2013, and testing my webapp. And I found that, when I login my website with (remember me?) checked . I'll sometimes can not logoff correctly. Then I find in debug tools,that each time when I logoff, It will request a new cookie with Authentication. How should I do with this situation?

This is the code for LogOff.

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult LogOff()
{
    AuthenticationManager.SignOut();
    return RedirectToAction("Index", "Home");
}

This is the problem where I think:

public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
    filters.Add(new System.Web.Mvc.AuthorizeAttribute());
    filters.Add(new HandleErrorAttribute());
}

除非您使用以下方法，否则它似乎并不总是能正确清除cookie：

AuthenticationManager.SignOut(DefaultAuthenticationTypes.ApplicationCookie);
