 The client closes the socket and the connection by dispatching a `1000: Normal Closure` close event to the server indicating a normal closure.
 
-## Keep-Alive
-
-The server will occasionally check if the client is still "alive", available and listening. In order to perform this check, implementation leverages the standardized [Pings and Pongs: The Heartbeat of WebSockets](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API/Writing_WebSocket_servers#Pings_and_Pongs_The_Heartbeat_of_WebSockets).
-
-Keep-Alive interval and the "pong wait" timeout can be tuned by using the accompanying configuration parameter on the server.
-
-Ping and Pong feature is a mandatory requirement by [The WebSocket Protocol](https://tools.ietf.org/html/rfc6455#section-5.5.2). All clients that don't support it are **not** RFC6455 compliant and will simply have their socket terminated after the pong wait has passed.
