Most likely not, but the client-instance can explicitly set it as a http-header from FLY_REGION
env var?
Similar to above, the client-instance can set this as http-header itself from FLY_APP_NAME
env var?
There isn’t a http load balancer at all in the 6pn
world. There’s a IP load-balancer if you allocate a Flycast 6pn
IP and connect to the other app instances via it.
