问题
I would want to set an absolute time out for the expiration for my sessions and not need it to be calculated based on lastAccessedTime. I have seen the issue https://github.com/spring-projects/spring-session/issues/922 . But my case is different from this case. With setting the expires time as absolute time in redis I can make sure the session does not cling for longer than I want in redis but also ensure session exists in the redis for the amount of time I require it to stay there even if there are no interactions with this session (basically don't want my session to end if there is a small inactivity period)
