http-parser este o bibliotecă C concepută pentru parsarea mesajelor HTTP de tip zero-copy, deconstrucția URL-urilor și gestionarea actualizărilor de protocol și a codificării chunked. Oferă utilitare pentru extragerea header-elor, metodelor și codurilor de stare din cererile și răspunsurile HTTP. Proiectul include un parser de URL-uri zero-copy pentru descompunerea șirurilor în componente individuale și un mecanism pentru detectarea cererilor de comutare a protocolului, pentru a identifica offset-ul exact de octeți unde încep datele non-HTTP. De asemenea, dispune de un decodor pentru gestionarea fluxurilor de date cu transfer codificat chunked.

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.
