WebSocket handles received Ping and Close messages automatically (as per the WebSocket Protocol) by replying with Pong and Close messages. If the listener receives Ping or Close messages, no mandatory actions from the listener are required.

These are used to notify the other side everything is still OK and to keep the connection open. Socket is a WebSocket client to interact with a WebSocket connection. You can use it to listen various events happening on the WebSocket connection and send messages to the server. Additionally, you can use socket.setTimeout() and socket.setInterval() to execute code in the background, or repeatedly, while the WebSocket connection is open.

Using this one can implement a heartbeat system to check if the connection is still alive. A ping or pong is just a regular frame, but it's a control frame. Pings have an opcode of 0x9, and pongs have an opcode of 0xA. When you get a ping, send back a pong with the exact same Payload Data as the ping (for pings and pongs, the max payload length is 125).

This payload may be overridden with the optional data argument which must be a string (which will be encoded to UTF-8) or a bytes-like object. Ping sends a ping to the peer and waits for a pong.

I have a websocket server built using play framework. It handles 10,000 connections. I have configured the client to send ping frames after every 120 secs to keep the connection alive. And I have set idle timeout at the server as 135 secs. My server is crashing when there are 10K connections. I suspect it might be due to the high traffic of
