# # Action Dispatch
#
# Action Dispatch is a module of Action Pack.
#
# Action Dispatch parses information about the web request, handles routing as
# defined by the user, and does advanced processing related to HTTP such as
# MIME-type negotiation, decoding parameters in POST, PATCH, or PUT bodies,
# handling HTTP caching logic, cookies and sessions.

        #{session_store.inspect} resolves to ActionDispatch::Session::#{session_store.to_s.camelize},

        Is #{session_store.inspect} spelled correctly, and are any necessary gems installed?
