Session (ci, native, db, what ?)

[eluser]Phil Sturgeon[/eluser]
These are all just various different ways of storing session variables. CI uses a library that either uses $_SESSION or inserts them into a database temporarily. Some of these are extensions to the native class and some are just replacements with some snazzy extras.

From reading through the descriptions it sounds like OB Session is the best as it not only allows you to control timeouts, auto-regeneration and other things, but you can make it use cookies or database storage which is a little more useful than good old sessions.
