How to make PHPSESSID permanent in Yii2?
My PHPSESSID is used as the user's access/identity token (authKey and id in the IdentityInterface implementation) and it shouldn't change. Presumably, this is bad from a security point of view, but it doesn't matter, in the first place you need to make it permanent, and then think about when it can be changed.
