NanoHTTPD is a lightweight, embeddable HTTP server for Java applications. It allows developers to integrate web server capabilities directly into a Java project to handle incoming requests without requiring a standalone installation. The project provides specialized implementations for an HTTPS web server, a WebSocket server for bidirectional real-time communication, and a static file web server. These capabilities enable secure network traffic through SSL certificates and the delivery of local files with automatic MIME type detection. The server includes systems for request routing and hand

http-parser es una librería en C diseñada para el análisis (parsing) de mensajes HTTP sin copia (zero-copy), deconstrucción de URLs y gestión de actualizaciones de protocolo y codificación fragmentada (chunked encoding). Proporciona utilidades para extraer cabeceras, métodos y códigos de estado de las peticiones y respuestas HTTP. El proyecto incluye un parser de URLs zero-copy para descomponer cadenas en componentes individuales y un mecanismo para detectar peticiones de cambio de protocolo, identificando el desplazamiento exacto en bytes donde comienzan los datos no HTTP. También cuenta con un decodificador para manejar flujos de datos con transferencia codificada por fragmentos.

http-parser is a C-based library for extracting request and response metadata from raw HTTP data streams. It utilizes a state-machine approach to identify message segments and boundaries. The project implements zero-copy string parsing and pointer-based URL deconstruction to avoid memory allocations and data duplication. It supports incremental stream processing to handle fragmented data chunks and includes mechanisms for decoding chunked encoding and managing network protocol upgrades.

wstunnel is a tool that tunnels arbitrary TCP traffic through WebSocket connections, enabling communication across restrictive firewalls and proxies. It operates as both a client and server, encapsulating TCP data within WebSocket binary frames and multiplexing multiple connections over a single WebSocket link. The tool supports mutual TLS authentication, requiring clients to present signed certificates for verification before establishing a tunnel, and provides shared secret access control and tunnel forwarding restrictions for additional security. The project distinguishes itself by offerin

This is a minimal WebSocket library for Go designed for bidirectional real-time communication.
