WebSocket vs long polling
Which best describes when WebSockets beat long polling?
Options
- 1When the server has no spare persistent-connection capacity and must shed long-lived sockets under heavy connection load
- 2When traffic is purely request/response with no server push and every single call is independent of the others
- 3When you need low-latency server-initiated push with bidirectional low-overhead messaging (e.g. chat, live collaboration)
- 4When you must use plain HTTP/1.0 and cannot rely on a persistent upgraded TCP connection surviving between requests
