websockets

WebSockets are a communication protocol that enables full-duplex communication over a single TCP connection. Unlike traditional HTTP requests, which are request-response based, WebSockets provide a persistent connection between a client and a server. This allows for real-time data transfer, where the server can push updates to the client without the client needing to repeatedly request them. This is particularly useful for applications like chat applications, online games, and live data feeds, where low latency and immediate updates are crucial. WebSockets begin with a handshake initiated by the client via HTTP. If the server supports WebSockets, it upgrades the connection from HTTP to WebSocket. After the handshake, data can be sent back and forth in both directions until the connection is closed by either party. The WebSocket protocol reduces overhead compared to HTTP because there are no HTTP headers included with each message after the initial handshake, resulting in faster and more efficient communication.
