Thomas Graves commented on SPARK-3168:
--------------------------------------
Spark is using the ServletContextHandler. Which has an option to create
sessionManager but is not there by default. I never added support for it as
many basic filters do not need it.
I do not know anything about CAS and haven't done much with sessions
themselves. It looks like we would have to investigate more what is really
needed by CAS. Is any session manager ok, specific ones, what else on the
backend do we need to do with clearing sessions or saving them, etc. I would
consider this a new feature.
