session_store(new_session_store = nil, **options)

Specifies what class to use to store the session. Possible values are :cookie_store, :mem_cache_store, a custom store, or :disabled. :disabled tells Rails not to deal with sessions.

Additional options will be set as session_options:

config.session_store :cookie_store, key: "_your_app_session"
config.session_options # => {key: "_your_app_session"}

If a custom store is specified as a symbol, it will be resolved to the ActionDispatch::Session namespace:

# use ActionDispatch::Session::MyCustomStore as the session store
config.session_store :my_custom_store
