Configuring the Directory where Session Files are Saved

By default, Symfony stores session metadata on the filesystem. If you want to control this path, update the framework.session.save_path configuration key:

framework:
    session:
        handler_id: session.handler.native_file
        save_path: '%kernel.project_dir%/var/sessions/%kernel.environment%'

Storing Sessions Elsewhere (e.g. database)

You can store your session data anywhere by using the handler_id option. See Configuring Sessions and Save Handlers for a discussion of session save handlers. There are also articles about storing sessions in a relational database or a NoSQL database.
