一共有3个目录，登录之后首先进入目录A, 然后通过 在A目录里面的页面菜单可以跳转到B和C。
目前A和B里面的页面进行跳转时，cookie都是存在的，就是从A跳转到C目录里面的页面时，cookie就都为空了。
真实搞不懂啊，各种Path,Domain Expires都设置了，就是不行。
WebCookieUtility.UserID = dt.Rows[0]["id"].ToString();
WebCookieUtility.Username = dt.Rows[0]["Username"].ToString();
WebCookieUtility.UserRealName = dt.Rows[0]["RealName"].ToString();
Response.Cookies["aaa_Userid"].Expires = DateTime.Now.AddDays(1);
Response.Cookies["aaa_Username"].Expires = DateTime.Now.AddDays(1);
Response.Cookies["aaa_UserRealName"].Expires = DateTime.Now.AddDays(1);
Response.Cookies["aaae_Userid"].Path = "/";
Response.Cookies["aaa_Username"].Path = "/";
Response.Cookies["aaa_UserRealName"].Path = "/";
string domain = ConfigurationManager.AppSettings["CookieDomain"];
Response.Cookies["aaa_Userid"].Domain = domain;
Response.Cookies["aaa_Username"].Domain = domain;
Response.Cookies["aaa_UserRealName"].Domain = domain;
Response.Cookies.Add(new HttpCookie("ASP.NET_SessionId", Session.SessionID));
哪个大神帮帮忙。
