Question

两个网站如果要用redis共享SESSION的话,那么这两个网站的域名必须这样配置吗?

比如 www.test.com 另外一个是 test.com的,必须采用这样的域名吗?
要让 .test.com的cookie 同时让两个网站能读取,这样理解对吧

Answer 1

No need, that is required for use in js

Answer 2

Shared sessions must have the same top-level domain name

Answer 3

Saving sessions in redis only changes the medium for storing sessions, and has nothing to do with the domain name.
