WebSockets

Created for the need of low latency and high bandwidth web app traffic like that of social media chat windows.

WebSocket features:

• Full duplex (send and rec simultaneously)

• Uses HTTP proto and port 443/80

• ws:// (websocket) and wss:// (secure websocket)

• no polling, send when you have data.

Basic WS usage:

Connect

var ws=new WebSocket('ws://<WebsocketServerURL>');

WebSockets themselves are not insecure but they do fall victim to vulnerabilities in how the data is used if unsanitized.
