Detailed Description

WebSocket Protocol Implementation for Real-Time Bidirectional Communication #include< websockets.h>
.

Overview

The NetBurner WebSocket implementation provides full-duplex communication channels over a single TCP connection, enabling real-time data exchange between clients and servers. WebSockets upgrade from HTTP connections and maintain persistent connections for efficient, low-latency bidirectional messaging.

Key features include:

• RFC 6455 compliant WebSocket protocol implementation
• Automatic connection upgrade from HTTP to WebSocket
• Support for text and binary data frames
• Built-in ping/pong for connection health monitoring
• Efficient buffering and flow control
• Support for both client and server roles
• Graceful connection closure with status codes
• Frame fragmentation for large messages
