HttpOnly Cookie的问题

Question

我在创建HttpOnly cookie时遇到问题，我使用以下代码来创建新cookie：

    //A.aspx
    HttpCookie ht = new HttpCookie("www");
    ht.Value = "www";
    ht.Name = "www";
    ht.HttpOnly = true;
    ht.Expires = DateTime.Now.AddDays(1);
    Response.AppendCookie(ht);
    Response.Redirect("B.aspx");

    //B.aspx
    HttpCookie cookie = Request.Cookies["Allowed"];
    HttpCookie htt = Request.Cookies["www"];
    if (cookie != null)
    {
        Response.Write(cookie.HttpOnly);
        Response.Write(htt.HttpOnly);
    }
    else
    {
        cookie = new HttpCookie("Allowed");
        cookie.HttpOnly = true;
        cookie.Value = "ping";
        cookie.Expires = DateTime.Now.AddMinutes(2);
        Response.Cookies.Add(cookie);  
        Response.Write(cookie.HttpOnly);
        Response.Write(htt.HttpOnly);

    }

问题是，尽管HttpOnly属性设置为True，但最终结果始终是：False。

有人能给我解释一下这个问题吗？

谢谢

浏览器不会将Cookie参数(过期日期、路径、HttpOnly等)发送回服务器，而只是将值发送回服务器。把它们送回去只会带来不必要的臃肿。因此，Request.Cookies中的cookies将只包含名称和值。

如果您想查看cookie值是否生效，请使用Firecookie或类似的工具来检查HttpOnly。或者尝试在JavaScript中访问它们--这就是它应该阻止的。
