These feature flags were enabled by default. We specifically disallowed
the use of automatic refresh with the SSO mode, though this poses some
complexity if using the forward-auth feature.
To simplify configuration and code, we remove the flags in their
entirety as session refresh behaviour is mostly already handled by the
implementation of GetSession() in the handlers. Specifically:
- the Standalone handler needs to refresh sessions when reverse-proxying
to the upstream.
- the SSO server handler needs to refresh sessions only when using the
forward-auth feature. It does not have an upstream to reverse proxy
to.
- the SSO proxy handler is a read-only upstream proxy and does not
possess the ability to refresh sessions itself, though it will
delegate traffic for the session endpoints to the configured SSO server.
Automatic refreshing is thus only disabled when running in SSO mode
without the forward-auth feature.
