# Round-Robin Load Balancing

# Default strategy. Cycles through endpoints in order; each backend
# receives an equal share of requests.

# Usage:
#   cargo run -p praxis-proxy -- -c examples/configs/traffic-management/round-robin.yaml
#   for i in $(seq 1 9); do curl -s http://localhost:8080/; echo; done
