Rails - Jul 2009 - duration of session

Hi everyone,

how to set the duration of a session? Does
"ActionController::Base.session_options[:new_session] = ... " work?
Another question is if i am using database for session storage, when a
session expires, will rails automatically remove the session record
from database for me?

thanks in advance,
xiahong

Nope. sessions never expire in that sense: the cookie containing the  
session id will die when the user exits their browser but your app  
does not (and in general cannot) know about that. It''s up to you to  
periodically clean out old rows from the sessions table.

Assume session is deleted before the cookie holding its id expires, what
happens when client contacts server with this session id? does rails
allocate a new session with a different ID to replace this old session?
