Are you 100% sure that the AOL clients are switching IPs during the transaction?

What you are probably seeing is the load balancer switching web servers and the client is losing the session. Try setting the load balancer to "bind" the browser IP to a specific web server for a specific time. This way they always hit the same web server and the cookie / session info should not be lost.

The other way is to move to DB sessions, so you can hit either web server and get the proper session info from the Database.
