Session expiration support for ActiveRecordStore, 0.1.0

This plugin allows to check when the current session will expire based on the updated_at column of the sessions-table. Sessions will not expire automatically, you have to handle them by yourself.

Installation

 ruby script/plugin install http://expire-sessions.rubyforge.org/svn/trunk/expire-sessions/

Usage

Somewhere in a controller (probably a authentication before_filter):

 if session.expired?
   reset_session
   flash[:warning] = 'Your session has expired'
 end

You can set the lifetime of your sessions. This is an application-wide setting and should be placed in an initializer.

 CGI::Session.lifetime = 20.minutes

You can also remove all expired sessions from the database by calling

 CGI::Session.delete_expired

directly in your code, or by using the provided rake-task

 rake db:sessions:delete_expired RAILS_ENV=production

It is very much recommended to set RAILS_ENV when using the rake-task.
