[November 22, 2024] Websocket connection limit update

Connection instructions:
Connection limit: 300 connection requests/IP/5min, Max 100 connections/IP
Subscription limit: 240 subscription requests/Hour/connection, Max 1000 channel subscription/connection

If there’s a network problem, the system will automatically disconnect the connection.

To keep the connection stable:

1. Websocket will be forcibly disconnected every 24 hours, please add the reconnection mechanism in your code
2. Users set a 30 seconds timer to a send string "ping", and expect a string "pong" as response. If no string "pong" received, please reconnect
3. Websocket server will disconnect the connection if there is no string "ping" received for 2 min
4. The Websocket server accepts up to 10 messages per second. The message includes:

• String "ping"
• JSON message, such as subscribe, unsubscribe.

5. If the user sends more messages than the limit, the connection will be disconnected. The IP which is repeatedly disconnected may be blocked by the server
6. We highly recommend you to subscribe less than 50 channels in one connection. The connections with less channel subscriptions will be more stable.
