Session Favorites
The Session Favorites module provides a "Favorites" or bookmark system based solely on a browser cookie. This allows site visitors to aggregate lists of content without becoming full-fledged users.
The module can be configured on a per-node-type basis, and optionally provides AJAX add/remove links.
Versions 6.x-1.3 and above depend on the Session API module.
The Session Favorites module is developed and maintained by OpenSourcery.
Drupal 7
This module will not be ported to Drupal 7, given that the Flag module now integrates with Session API to provide the functionality (in a much more flexible way) of Session Favorites.
