问了个问题哟
我今天下午 我在taobao搜索下了 照片墙
然后晚上的时候 我想看点技术方面的东西
我就打开了 http://www.360doc.com/content/05/1221/14/3500_47550.shtml 讲curl的
这个地址里面有一个嵌套了一个taobao推广的 iframe
然后里面推广的全是 照片墙的 东西
以前也遇到过 在淘宝搜索了的东西 上其他网站的时候也能收到相关产品的推广
我想知道他们大概是怎么做的
在其他域下知道我在淘宝搜索了什么产品.............
------解决方案--------------------
……
你没搞清楚我说的话
你虽然访问的是A网站，但iframe里面的内容是淘宝的，不是A网站
网站间不能直接跨域访问cookie，除非用API
