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
