Does spring cloud gateway/loadbalancer keep the connection alive?

Question

I have set up a Docker Swarm with the whoami service that is replicated 20 times. From the gateway container when I do wget -qO - whoami or the wget -qO - 10.0.x.x IP address I get random whoami replicas. However, when I do a similar thing on Spring Cloud Gateway it keeps on hitting the same replica.

Is there something in Spring Cloud Gateway or Load Balancer that keeps the connection stuck to the same node?

Also is it possible to disable that so I can test round robin

BOM is set('springCloudVersion', "2021.0.1")

Relevant blocks of application.yml. No discovery just a simple route.

spring:
  cloud:
    gateway:
      routes:
        - id: after_route
          uri: http://whoami2
          predicates:
            - Path=/who

Yields the following output
