Ps: Because Google Chrome recently change the behavior about Cookie's
samesite default to
Lax,I'm not really sure which cookie in my app will affected by this change.
As I know, when on website
www.a.com we can't set cookie which domain is
.b.com.Does this happen because the Same Origin Policy or anything else?
Can I set a cookie which attribute domain is
.a.b.com so that only request to
www.a.b.com will send with this cookie but request to
www.b.com will not?
