asp.net 二級功能變數名稱表單認證情況下共用Cookie

   二級功能變數名稱之間共用Cookie，很重要的一點就是配置,如下：

domain設置為.ahdqxx.com，如果你的功能變數名稱是www.ahdqxx.com,mall.ahdqxx.com,那麼請設置你的domain為.ahdqxx.com

path設置為/

<authentication mode="Forms">
      <forms name="DQ.AUTH" loginUrl="http://www.ahdqxx.com/Login/Index" protection="All" domain=".ahdqxx.com" timeout="43200" path="/" requireSSL="false" slidingExpiration="true" />
    </authentication>

第二重點的就是登陸時候Cookie設置，

不要忘記使用之前配置的東西來設置 Cookie（FormsAuthentication.FormsCookiePath，FormsAuthentication.CookieDomain）

      public virtual void SignIn(Customer customer, bool createPersistentCookie)
        {
            var now = DateTime.UtcNow.ToLocalTime();

            var userdata = JsonConvert.SerializeObject(new SimpleUser { Name = _customerSettings.UsernamesEnabled ? customer.Username : customer.Email, ID = customer.CustomerGuid });

            var ticket = new FormsAuthenticationTicket(
                1 /*version*/,
                _customerSettings.UsernamesEnabled ? customer.Username : customer.Email,
                now,
                now.Add(_expirationTimeSpan),
                createPersistentCookie,
                userdata,
                FormsAuthentication.FormsCookiePath);



            var encryptedTicket = FormsAuthentication.Encrypt(ticket);

            var cookie = new HttpCookie(FormsAuthentication.FormsCookieName, encryptedTicket);
            cookie.HttpOnly = true;
            if (ticket.IsPersistent)
            {
                cookie.Expires = ticket.Expiration;
            }
            cookie.Secure = FormsAuthentication.RequireSSL;
            cookie.Path = FormsAuthentication.FormsCookiePath;
            if (FormsAuthentication.CookieDomain != null)
            {
                cookie.Domain = FormsAuthentication.CookieDomain;
            }

            _httpContext.Response.Cookies.Add(cookie);
            _cachedCustomer = customer;
        }

容易犯得的錯誤，如果你在配置中使用了machineKey節點，請保證相關站點使用相同的machineKey
