异步提交不能用COOKIE吗

Question

我用的是AjaxPro.2.dll [AjaxPro.AjaxMethod]
    public string GetIsUrl(string strUserFrom)
    {
        try
        {
             if (Request.Cookies["user"] != null)
            {
                string CookieUser = strUserFrom;
                SqlDataReader Mydt = ol.ShowOnline(CookieUser);
                if (Mydt.Read())
                {
                    ol.UpdateOnline(CookieUser, DateTime.Now.ToString());
                }
                else
                {
                    ol.InsertOnline(CookieUser);
                }
                Mydt.Close();
                Mydt.Dispose();
                DataTable dt = ch.ShowSendMsg(CookieUser);
                int i = 0;
                while (i < dt.Rows.Count)
                {
                    Guid u = Guid.NewGuid();
                    string dsfs = u.ToString();
                    string dsfs1 = u.ToString();
                    string userid = dt.Rows[i]["YUser"].ToString();
                    ch.UpdateSendMsgByAuit(dt.Rows[i]["id"].ToString());
                    string Url = "../ChatRoom.aspx?" + dsfs1 + "&from=" + CookieUser + "&to=" + userid + "&" + dsfs;
                    i++;
                    return Url;
                }
            }
            return "";
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }
 if (Request.Cookies["user"] != null) 这句出异常，“请求在此上下文中不可用”

Answer 2

ajaxPro要获取Cookies和Session的话，需要在方法上加一个属性。 具体的是什么，最好查下帮助。
