I do not know the answer to the connection question but I may be able to help on the session question.
Now, if you are referring to session replciation between two ACE modules? If so, you can do 'sho sticky database detail' and you will see two lines at the bottom of each entry for
created-from-HA-peer: FALSE
HA-replicated-at-least-once: TRUE
Now if you wanting to see if sticky sessions are divided evenly between the rservers, I often use
sh sticky database group | inc | count
and then run that for both real servers and will show how many sticky entries are on each real server.
