== Session Messages ==

This page is meant to evaluate some of the different session/cookie message/notification engines out there for potential inclusion in Django as a contrib app.  It is a work in progress so please contribute (your notification engine here) or other changes as you see fit.

For more information see:
 * Ticket #4604
 * http://groups.google.com/group/django-developers/browse_thread/thread/eba93088c649022b
 * http://www.caktusgroup.com/blog/2009/06/19/towards-a-standard-for-django-session-messages/

=== Criteria ===

Criteria necessary for inclusion in the core:

 * Support message passing for anonymous users
 * Avoid database/cache queries if possible
 * Support larger messages that don't fit in a cookie (> 4kb)
 * Don't lose messages if they're not displayed to the user (lazy message loading)
 * Signs cookie-based messages
 * Provide a standard, intuitive interface so that reusable apps can provide feedback related to the current session
 * Needs community approval/support
 * Needs to be the "de facto" standard implementation

=== Available Options ===

||'''Name and Link'''||'''Anonymous user support'''||'''Minimal DB Access'''||'''Supports messages > 4kb'''||'''Lazy loads messages'''||'''Signed cookies'''||'''Standard interface'''||

 * '''yes''' means yes, always
 * '''sometimes''' means under certain conditions (e.g., an engine might support large messages if the session is used, and avoid DB access if a cookie is used, but not both)
 * '''no''' means no, not in the current implementation

Please update this table with new options or corrected information as necessary.
