We have used file based sessions historically for performance reasons. We are migrating to 2.2 at the moment and I would like to review this situation. I was concerned to read a code comment:
// legacy limited file based storage - some features and auth plugins will not work, sorry
Can anyone offer any information on which features and auth plugins will not work? Might we be forced to move to database sessions?
Sorry if this info is out there already but I haven't found anything yet.
