是否可以在域和子域名之间共享Cookie [英] Is it possible to share a cookie between a domain and a subsubdomain

问题描述

我尝试在www.example.com和admin.other.example.com之间分享Cookie。b我可以将其与other.example.com一起使用，但没有办法访问子子域

I'm trying to share a cookie between www.example.com and admin.other.example.com I've being able to make it work with other.example.com, but there's no way to access the sub-sub-domain

编辑：我通过将Cookie域定义为.example.com来处理子域（请注意第一个点）

I handle subdomains by defining the cookie domain as .example.com (note the first dot)

推荐答案

您只能在域与其自己的子域之间共享Cookie。
例如：

You can only share cookies between a domain and its own subdomains. For example:

• 为域 example.com定义的Cookie 可以通过 www.example.com 和 foo.bar.example.com
$ b访问$ b
• 为 www.example.com 定义的Cookie可以通过 foo.www.example.com ，但不是 bar.example.com

• a cookie defined for the domain example.com can be accessed by www.example.com and foo.bar.example.com
• a cookie defined for the domain www.example.com can be accessed by foo.www.example.com but not by bar.example.com
