如果要启用Cookie的即时吊销，则每个请求都必须命中数据库以验证Cookie。因此，延迟之间的权衡在于数据库负载。但是您始终可以将validationInterval设置为0。

app.UseCookieAuthentication(new CookieAuthenticationOptions
{
    AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
    LoginPath = new PathString("/Account/Login"),
    Provider = new CookieAuthenticationProvider
    {
        // Enables the application to validate the security stamp when the user logs in.
        // This is a security feature which is used when you change a password or add an external login to your account.  
        OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
            validateInterval: TimeSpan.FromSeconds(0),
            regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))
    }
});
