跨子域共享Cookie后，SignInManager SignOutAsync无法正常工作

Question

对于多子域中的SSO，我基于Share cookies across subdomains设置了RelevanceRelationValue：

entity=some_value1

设置cookie的域后，options.Cookie.Name='.example.com'不会注销用户，并且身份验证cookie也不会删除。 我尝试手动删除Cookie，但不起作用：

         services.ConfigureApplicationCookie(options => {
            options.Cookie.Name = "Cookie1";
            options.Cookie.Domain = ".example.com";
            options.LoginPath = "/Identity/Account/Login";
            options.LogoutPath = "/Identity/Account/Login";
            options.AccessDeniedPath = "/Identity/Account/AccessDenied";
        });
