How can we disable the session to expire automatically in rails?-CodePudding

how can we have a Rails application without a session expiring automatically within specific period of time. Or if the question can't bring a clear picture, is it okay to just delete the the line expire_after: 3.day, from

config.middleware.use(
      ActionDispatch::Session::CookieStore,
      key: '_myApp_session',
      expire_after: 3.day,
      serializer: :json

  )

not to expires the session automatically?

Thanks in advance

ActionDispatch::Session::CookieStore extends this class from Rack https://rubydoc.info/gems/rack/Rack/Session/Abstract/Persisted which sets the deafult expire_after to nil, which in reality is 20 years from the moment the cookie gets saved, so deleting the option should give you a somewhat permament by default cookie. However cookies already saved before the change, will still expire after the period specified, only after getting saved with new option they will become permament.
