The typical value for this interval is 30 seconds (as defined by the OS or the .NET platform). It is used to initialize KeepAliveInterval value. Applies to The data argument allows a small amount of data (up to 125 bytes) to be sent as a part of the ping message. Note that not all websocket implementations expose this data to applications.

Example: send a ping every 30 seconds The main loop of the Websocket server is idle for a maximum of 4 seconds, even if there is nothing to do. After that time interval has elapsed, this loop optionally sends a magic string to the client. This can be configured using the special setting: WS4REDIS_HEARTBEAT = '--heartbeat--' The interval between ping signals.
