| 4 | Template which tests Neutron load balancing requests to members of |
| 5 | Heat AutoScalingGroup. This uses LBaas V2. |
| 6 | Instances must be running some webserver on a given app_port |
| 7 | producing HTTP response that is different between servers |
| 8 | but stable over time for given server. |
