请教一下代码的问题，重复提交有关的

Question

我下面写的测试时有效果，但是传到服务器上就没用了或者哪位大大有更好的方法 请教！！！！flink.aspx里的：                HttpCookie cookie = Request.Cookies["time"];
                if (cookie != null)
                {
                    if (DateTime.Compare(Convert.ToDateTime(cookie.Value), DateTime.Now) < 30)
                    {
                        Response.Write("禁止在30秒内连续提交");
                    }
                }
                else
               {
                    Response.Cookies["time"].Value = DateTime.Now.ToString();
                            Response.Cookies["time"].Expires = DateTime.Now.AddSeconds(30);
                            Response.Write("<script>alert('申请成功'),window.location.replace('test.htm');</script>");
                  }
test.htm里就是一张指向flink.aspx的表单
