Loadbalancer and UI configuration

Problem

-- When using a loadbalancer in front of a clustered UI and webtrader, pictures might not load and sessions can get disconnected. Logging in may fail as well.

Resolution

The loadbalancer needs to be configured to persist the session on one target UI machine and not switch between targets within one session. This can be accomplished by configure the persistence of a session based on the JSESSIONID cookie.
