奇怪了，不能写入COOKIE。高分求解决办法。

Question

今天刚重装服务器系统，装好了后就不能写入COOKIE了。下面是写入COOKIE的类，大家看看哪出问题了？是代码？还是服务器？public static string ReadCookie(Page ThisP, string CookieSaveName, string Key)
{
      string text2;
      MethodDefine1.Null();
      long num1 = XenoCode.User.Profile.Profile.OnEntry(0x1d);
      if (DateTime.Now > DateTime.Parse(string.Intern(d4485e5ae14ac128.cc381ffa3ede662f("\ud2e4\ud9df\ue0dd\ue7e2\ueed3\uf5d3\ufcd1\u03ca\u0aca\u11c8", 0x4fdad2b2))))
      {
            text2 = "";
      }
      else
      {
            string text1 = CookieSaveName;
            if (CookieSaveName == "")
            {
                  text1 = ThisP.Request.Url.Host;
            }
            HttpCookie cookie1 = ThisP.Request.Cookies[text1];
            if (cookie1 == null)
            {
                  text2 = "";
            }
            else
            {
                  try
                  {
                        text2 = cookie1[Key].ToString();
                  }
                  catch
                  {
                        text2 = "";
                  }
            }
      }
      XenoCode.User.Profile.Profile.OnExit(num1);
      return text2;
}
