而我正在使用Katana的Microsoft.Owin.Security.Cookies来进行表单验证.我收到了Set-Cookie标头,但是Cookie并没有被保存,也没有包含在下一个请求中.所以有什么问题？我做错了什么？

欧文启动：

app.UseCookieAuthentication(new CookieAuthenticationOptions()
        {
            AuthenticationMode = AuthenticationMode.Active,AuthenticationType = "GM",CookieHttpOnly = true,CookieSecure = CookieSecureOption.SameAsRequest,CookiePath = "/",CookieName = CookieAuthenticationDefaults.CookiePrefix + "GM",CookieDomain = "localhost",});

控制器代码：

var context = Request.GetOwinContext();
context.Authentication.SignIn(new AuthenticationProperties()
    {
        IsPersistent = true
    },new ClaimsIdentity(new[] {new Claim(ClaimsIdentity.DefaultNameClaimType,user.Login)},"GM"));
context.Response.Headers.Add("Location",new []{ "/" });
return Request.CreateResponse(HttpStatusCode.Found);
