Under what conditions is polling better than streaming?

[carenot]

Thanks for the informative post. I have a question about streaming.

When you say streaming, do you mean http streaming (where a client opens a long standing http connection when sending create_session request)? Does websocket follow the same behavior (opening a websocket channel and the server keeps pushing updates to the client)? If not, how does LS work in websocket exactly?

Thanks

Streaming and polling can be combined with HTTP and WebSockets, so that all the combinations are possible and make sense. So:
1) Streaming over HTTP
2) Streaming over WebSocket
3) Polling over HTTP
4) Polling over WebSocket

Lightstreamer automatically chooses the best combination for each connection.
