Server Configuration


The configuration of a Web server really depends on the server itself. There is no standard approach.

Load Balancer (Required)

Be sure to configure sticky session on your load balancer because ZK only works correctly on this setting. [1]

  1. ↑ Check ZK DesktopImpl.java, you will see there are lots of synchronized used in many methods including:
    • generate desktop ID
    • addPage(), removePage()
    • enableServerPush()
    • processing server push update
    The keyword synchronized only works in single JVM, so it’s impossible to keep the same state between 2 different nodes of a clustering even with session replication if 2 nodes receive 1 requests at roughly the same time. Each AU request changes a Desktop's status of a session, if 2 AU requests are processed by 2 different clustering nodes and each one has its own session, then one session state might override another session.
