ARServer does not have a session per say as all authentication information is sent in each packet, but each ARServer does keep track of what licenses are allocated to a given account. This is why you can connect to a Remedy server through the user tool, bounce the Remedy server, and still use the same User tool session to access the Remedy server after the restart. The problem comes into play with floating licenses since a user can cause a floating license allocation on each ARServer.
The mid-tier stores information specific to a session in session attributes; the session attributes are a function of the servlet container. That is why you must re-authenticate to the mid-tier if it is restarted while you have an active session. The session specifics are not serializable between multiple instances of a servlet container, the mid-tier application does not use a central store/replication method to serialize the objects between multiple instances, so session persistence is required for each connection to a given mid-tier server. The web server in use may (optionally) track sessions.
