By default rails does not clear out stale sessions from the session store. To implement this feature I added the following small snippet of code;
class SessionCleaner
def self.remove_stale_sessions
CGI::Session::ActiveRecordStore::Session.
"destroy_all( ['updated_on end
end
And then invoke the remove_stale_sessions method every 10 minutes via;
