In attachment the session library used in ExiteCMS, which uses a previous_id field to save the session_id when it gets rotated.
It's a drop-in replacement for CI's session library (in application/libraries).
Some remarks:
- it's a CI 2.0 library, I haven't tested in in CI 1.7.2.
- it uses a different sessions table layout, you need to recreate the table
- it has sess_write() disabled by default
- it fixes a bug in the original where a custom flashkey is destroyed when updating flash variables
With regards to sess_write(): You need to call it with a parameter TRUE to write the session. ExiteCMS does this at the end of every page request, and when redirecting, so per page request only one session update is done (the original library updates the record every time you modify a session variable). If you don't want that, remove the check of this parameter in sess_write().
