procedure Ping; overload;

procedure Ping(const Data: TBytes); overload;



Call the Ping message to send a ping control message to a WebSocket server and wait for a response pong message from the server. If after the time specified in the Options.ReadWriteTimeout property, the client does not get a response from the server, the method will generate an error.

A Ping message may serve either as a keepalive or as a means to verify that the remote endpoint is still responsive.


Data is an array of bytes, which contains the sent message body.
