Firefox下利用Cookies出现跨二级域名不能提交购物车信息

Firefox下出现跨二级域名不能提交购物车信息

（问题在http://space.cnblogs.com/question/20513/）

  主域名  www.MySite.com

  商品目录  www.MySite.com/mall

 结算目录   member.MySite.com 

  用户在 主域名www.MySite.com  加入购物车的商品能在 商品目录  www.MySite.com/mall显示，在ie下能在 结算目录   member.MySite.com 显示进行结算，但在Firefox下却 显示购物车为空，但在

结算目录   member.MySite.com 下ie和Firefox都可以将商品加入购物车，进行结算。

 

下面是 加入购物车和显示购物车的代码，有做过类似的园友们给点意见，O(∩_∩)O谢谢了 
 

 加入购物车
