How are WebSockets kept alive?
WebSocket uses HTTP as the initial transport mechanism, but keeps the TCP connection alive after the HTTP response is received so that it can be used for sending messages between client and server. WebSockets allow us to build “real-time” applications without the use of long-polling.
Does WebSocket need keepalive?
TCP keepalive is automatic, and timed, when enabled, whereas WebSocket ping/pong is executed as required by the application. The WebSocket protocol specification defines Ping and Pong frames that can be used for keep-alive, heart-beats, network status probing, latency instrumentation, and so forth.
How long do WebSocket stay open?
1 Answer. A WebSocket connection can in theory last forever. Assuming the endpoints remain up, one common reason why long-lived TCP connections eventually terminate is inactivity.
Should I close WebSocket connection?
If you are writing a server, you should make sure to send a close frame when the server closes a client connection. The normal TCP socket close method can sometimes be slow and cause applications to think the connection is still open even when it’s not.
How do I find Websockets?
You can open the Chrome console (CTRL+SHIFT+J) then under the network tab you’ll find the websockets currently opened and you’ll be able to see the frames that have been exchanged with the server.

What is a WebSocket connection error?
Once a connection has been established between the client and the server, an open event is fired from the Web Socket instance. Error are generated for mistakes, which take place during the communication. The onerror event is fired when something wrong occurs between the communications.
Is WebSocket RESTful?
