I have an ZK hosted on multiple jetty instances behind a AWS load balancer with https enabled. But encounter response 502 when loading "zkau/web/ba6595e5/js/zul.lang.wpd"

May i know what is the correct configuration for ZK application with load balancing?

Since ZK applications use servlet sessions one key config is to use "sticky sessions".

zul.lang.wpd depends on the user locale (which can be determined by the session), so that could be causing the errors.
