I'd like to use different session id (PHPSESSID value) before and after login to the system:
$this->get("session")->set("PHPSESSID", session_create_id());
but after doing that cannot log onto system.
I found a solution here but I don't have security.xml file: Symfony 3 - How to keep session id after logging in?
Any solutions will be appreciated.
You can use
$this->get("session")->migrate();
It should create a new session identical to the current session.
More info here http://symfony.com/doc/3.4/components/http_foundation/sessions.html
