Hello, every one: I am newbie for drools and guvnor, so excuse me if the question is duplicated for others. I am use guvnor 5.5.0 final and set up two nodes guvnor cluster successfully. But I don’t know how to configure the knowledge agent to use the cluster for HA?(before the cluster set up a nginx for banlance?) Thx a lot
