conf/initializers/session_store.rb

opts = {}
if Rails.configuration.host == "myapplication.com"
  opts =  {expire_after: 2.months, domain: :all}
end

unless Rails.env.test?
  opts[:secure] = true
  opts[:same_site] = :none
end
opts[:key] = '__Host-'

Rails.application.config.session_store :active_record_store, **opts

附上github cookies的截图。我希望我的会话标头如图所示（前缀为 __Host-）。
