- avoid access denied on bad cookie, instead just nuke it
- avoid marking a token unseen for first minute post rotation
- log path in user auth token logs
This relaxes our security in the following way
- prev auth token is always accepted as long as rotation
date is within our window of SiteSetting.maximum_session_age.hours
(previously old token expired within a minute of new one being seen)
- new auth token is marked unseen if we are presented with an old token
after we already saw new one
This attempts to fix an issue where ios webkit is not committing new cookies
Revamped system for managing authentication tokens.
- Every user has 1 token per client (web browser)
- Tokens are rotated every 10 minutes
New system migrates the old tokens to "legacy" tokens,
so users still remain logged on.
Also introduces weekly job to expire old auth tokens.
