All Implemented Interfaces:

LoadBalancerStrategy<S>, Serializable

public class StickyRoundRobinStrategy<S extends ClientRequest>
extends RoundRobinStrategy<S>

this is the sticky round robin strategy implementation. this strategy delegates the requests to different servers each time. this way the load is balanced between more than 1 server. if multiple requstes are initialized from the same client using the same flowcontext it will be directed to the same server node.
