MVC 5会话问题

Question

更新1：如果我通过ajax请求设置会话，当js确实刷新当前操作时，我无法使用此会话。现在，如果我通过非ajax请求设置会话，那么这些请求也可以在其他控制器内部甚至是ajax动作中使用。

更新2 ：删除并添加有助于解决此问题的会话

<modules runAllManagedModulesForAllRequests="true">
      <remove name="Session" />
      <add name="Session" type="System.Web.SessionState.SessionStateModule"/>
    </modules>

我正在设置一个新站点，它使用表单身份验证，我正在验证活动目录。在成功进行身份验证后，我将用户类放入会话中，当我立即检查时，我可以。

//login user and put the user in session
AuthenticationHelper.LoginUser(user, loginModel.IsRememberMe);
//just checking
var userFromSession = AuthenticationHelper.GetUserFromSession();

public static void LoginUser(User user, bool isRememberMe)
        {
            //login user and put user in the session

            //log off first
            LogOff();

            //add user to session
            AddUserToSession(user);

            //sign in
            if (!isRememberMe)
            {
                //Set cookie
                FormsAuthentication.SetAuthCookie(user.UserId, false);
                /*
                GenericIdentity identity = new GenericIdentity(user.UserId);
                string[] roles = { person.PersonaType };
                GenericPrincipal principal = new GenericPrincipal(identity, roles);
                HttpContext.Current.User = principal;
                 */
            }
            else
            {
                //Create Persistent cookie
                var ticket = new FormsAuthenticationTicket(user.UserId, isRememberMe, 1);
                var encrypted = FormsAuthentication.Encrypt(ticket);
                var authCookie = new HttpCookie(FormsAuthentication.FormsCookieName, encrypted);
                authCookie.Expires = System.DateTime.Now.AddYears(1);
                if (HttpContext.Current != null)
                {
                    HttpContext.Current.Response.Cookies.Add(authCookie);
                }
            }
        }


public static void AddUserToSession(User user)
            {
                if (HttpContext.Current != null && HttpContext.Current.Session != null)
                {
                    HttpContext.Current.Session["SignedInUser"] = user;
                }
            }

            public static User GetUserFromSession()
            {
                User user = null;
                if (HttpContext.Current != null && HttpContext.Current.Session != null)
                {
                    user = (User) HttpContext.Current.Session["SignedInUser"];
                }
                return user;
            }

但是，当我在登录后的同一时刻刷新页面时，我的会话将返回null。在这种情况下， Request.IsAuthenticated为true，User.Identity.Name中包含我的用户名。

我在web.config中也有以下内容。

                  

我在这里缺少什么？

这是完整的web.config。要么我错过了web.config中的某些内容，要么是在干扰我的会话。
