Load balancing

Upstream servers Block

  • backup
  • down
  • slow_start=30s
  • max_conns
  • queue 100 timeout=70

  • least_conn
  • ip_hash
  • Generic hash $request_uri consistent
  • least_time
    • header
    • last_byte
    • last_byte inflight
  • random two least_time=last_byte

Session persistence

  • Sticky cookie
  • Sticky route
  • Sticky learn (most sophisticated server side cookie, not at client side)

SECURITY

TLS termination
