表单身份验证超时被忽略

我正在使用asp.net表单身份验证来要求用户在访问特定页面时登录。我希望用户在闲置5分钟后必须再次登录，但是无论我在web.config的“表单”的“超时值”部分中输入什么内容，用户都只能在会话状态过期后才能启动。

我尝试过的测试之一涉及此配置：

<system.web>   
<sessionState timeout="1" />
  <authentication mode="Forms">
      <forms loginUrl="~/authentication" timeout="2" slidingExpiration="true"/>
  </authentication>
</system.web>

如果我登录并闲置一分钟，则刷新页面时，系统会要求我再次登录。但是，我的印象是，在表单身份验证超时到期之前，我应该能够继续工作。我知道，在1分钟标记处，对于slideExpiration设置来更新我的cookie来说为时已晚，但是在cookie实际失效之前，我还应该再等一分钟。

如果我删除了Sessiontate超时部分，则在两分钟后不要求我登录。要求我重新登录需要很长时间（大约30分钟）。对我来说，这听起来像只在sessionState到期时才要求重新登录。

我在这里想念什么吗？

这是所涉及的控制器和方法的基本布局。首先，用户尝试转到“招聘人员”页面：

public class HireController : Controller
{
    [Authorize]
    public ActionResult Recruiter()
    {
      //do stuff after we've been authorized to access this page
    }
}

因为需要授权用户，所以他们被重定向到身份验证控制器中的登录页面：

public class AuthenticationController : BaseAuthenticationController
{
    private readonly IAuthenticationService AuthenticationService;
    public AuthenticationController(IAuthenticationService authService)
        : base(authService)
    {
        AuthenticationService = authService;
    }
    [AcceptVerbs(HttpVerbs.Get)]
    public ActionResult Index(string returnUrl)
    {
        var special= false;
        return View("~/Views/Login/Login.cshtml", new LoginModel(special) { ReturnUrl = returnUrl });
    }

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult Index(LoginCredentials credentials, string returnUrl)
    {
        try
        {
            if (!ModelState.IsValid)
            {
                throw new ApplicationException(GeneralError);
            }

            base.DoLogin(credentials.Username, credentials.Password);
        }
        catch (Exception ex)
        {
            string message = (ex is ApplicationException) ? ex.Message : GeneralError;
            ModelState.AddModelError("", message);
            return View("~/Views/Login/Login.cshtml", new LoginModel { Username = credentials.Username, ReturnUrl = returnUrl });
        }
        return RedirectToLocal(returnUrl);

    }

    private ActionResult RedirectToLocal(string returnUrl)
    {
        if (Url.IsLocalUrl(returnUrl))
        {
            return Redirect(returnUrl);
        }
        if (User.Identity != null && User.Identity.IsAuthenticated)
        {
            return RedirectToAction("Recruiter", "Hire");
        }
        return RedirectToAction("Recruiter", "Hire");
    }
}

这是BaseAuthenticationController类：

  public class BaseAuthenticationController : Controller
{
    private readonly IAuthenticationService AuthenticationService;
    protected const string GeneralError = "Login failure please try again";

    public BaseAuthenticationController(IAuthenticationService authService)
    {
        AuthenticationService = authService; 
    }

    public void DoLogin(string username, string password)
    {
        AuthenticationService.Login(username, password);
    }
}

这是具体的IAuthenticationService类：

 public class WebAuthenticationService : IAuthenticationService
{
    private const string InvalidError = "Invalid User Credentials Please try again";
    private const string LockoutError = "You have been locked out of the Hiring Center. You will receive an email shortly once your password has been reset.";
    readonly string uri = ConfigurationManager.AppSettings["HiringLoginApiBaseUrl"];
    private readonly ISecurityContext SecurityContext; 

    public WebAuthenticationService(ISecurityContext securityContext)
    {
        SecurityContext = securityContext; 
    }

    private LoginResult GetUserLogin(string username, string password)
    {
        using (var httpClient = new HttpClient())
        {
            httpClient.BaseAddress = new Uri(uri);
            var content = new FormUrlEncodedContent(new[] 
            {
                new KeyValuePair<string, string>("username", username),
                new KeyValuePair<string, string>("password", password)
            });
            var postResult = httpClient.PostAsync("/api/Login/Post", content).Result;                
            var loginResult = postResult.Content.ReadAsAsync<LoginResult>().Result;

            return loginResult;
        }
    }

    public MembershipProvider AuthenticationProvider
    {
        get { return Membership.Provider; }
    }

    public void Login(string userName, string password)
    {
        var loginResult = this.GetUserLogin(userName, password);
        if (!loginResult.IsValid)
        {
            throw new ApplicationException(InvalidError);
        }

        if (loginResult.IsLockedOut)
        {
            throw new ApplicationException(LockoutError);
        }

        // Maintain the location
        IUser current = SecurityContext.Current;

        SecurityContext.SetCurrent(User.CreateAuthorized(userName, current.Location, current.Preferences));
        FormsAuthentication.SetAuthCookie(userName, false);

    }
}

对于WebAuthenticationService类中的以下行，我不太清楚：

SecurityContext.SetCurrent(User.CreateAuthorized(userName, current.Location, current.Preferences));

SetCurrent（）方法的定义如下：

 public class HttpSecurityContext : ISecurityContext
{
    public static string SECURITY_CONTEXT_KEY = "SECURITY_CONTEXT";

    public IUser Current
    {
        get
        {
            IUser user = HttpContext.Current.User as IUser;
            if (user == null)
            {
                throw new ApplicationException("Context user is invalid;");
            }
            return user;
        }
    }

    public void SetCurrent(IUser user)
    {
        HttpContext.Current.User = user;
    }
}
