how can I get the active_record_store :domain option in my controller

[Erwin]

I initialized it :

Rails.application.config.session_store :active_record_store, :key => '_yoogroop_session', :domain => {

  production: 'yoogroop.com', 

  development: 'lvh.me'}.fetch(Rails.env.to_param.to_sym, :all)

and I need to get the :domain value in my controller

cookies.delete(:login, :domain => # initialized :domain value in activer_record_store 1)

any clue ?

thanks
