services.yml

services:
    # ...
    app.authentication_success_handler:
        class: AppBundle\EventListener\AuthenticationSuccessHandler
        tags:
            - { name: kernel.event_listener, event: security.interactive_login, method: onSecurityInteractiveLogin }

@emrevural20 Yes $request->headers->get("referer"); works!
