# For removing objects from the session, you can either assign a single key to nil, like <tt>session[:person] = nil</tt>, or you can

- # By default, sessions are stored on the file system in <tt>RAILS_ROOT/tmp/sessions</tt>. Any object can be placed in the session
- # (as long as it can be Marshalled). But remember that 1000 active sessions each storing a 50kb object could lead to a 50MB store on the filesystem.
- # In other words, think carefully about size and caching before resorting to the use of the session on the filesystem.
+ # Sessions are stored in a browser cookie that's crytographically signed, but unencrypted, by default. This prevents
+ # the user from tampering with the session but also allows him to see its contents.
#
- # An alternative to storing sessions on disk is to use ActiveRecordStore to store sessions in your database, which can solve problems
- # caused by storing sessions in the file system and may speed up your application. To use ActiveRecordStore, uncomment the line:
+ # Do not put secret information in session!
+ #
+ # Other options for session storage are:
+ #
+ # ActiveRecordStore: sessions are stored in your database, which works better than PStore with multiple app servers and,
+ # unlike CookieStore, hides your session contents from the user. To use ActiveRecordStore, set
#
# config.action_controller.session_store = :active_record_store
#
# in your <tt>environment.rb</tt> and run <tt>rake db:sessions:create</tt>.
#
+ # MemCacheStore: sessions are stored as entries in your memcached cache. Set the session store type in <tt>environment.rb</tt>:
+ #
+ # config.action_controller.session_store = :mem_cache_store
+ #
+ # This assumes that memcached has been installed and configured properly. See the MemCacheStore docs for more information.
