For reference, since it’s not specifically in the environment.rb file and
apparently no one else on the net found it necessary to place on a
Google-accessible page, the proper syntax for switching from file-based session
stores to DRb session stores in Rails
(0.14 and onwards) is config.action_controller.session_store = :drb_store
inside the Rails::Initializer block.
From what I can tell, from the contents of the ActionPack’s
lib/action_controller/session/ directory, the other options are
:active_record_store and :mem_cache_store. This is actually confusing, since
I thought the file store class would have been there, but it’s not.
