C++ websocket client/server library
WebSocket++ is a header only C++ library that implements RFC6455 The WebSocket
Protocol. It allows integrating WebSocket client and server functionality into
C++ programs. It uses interchangeable network transport modules including one
based on raw char buffers, one based on C++ iostreams, and one based on Asio
(either via Boost or standalone). End users can write additional transport
policies to support other networking or event libraries as needed.
Major Features
- Full support for RFC6455
- Partial support for Hixie 76 / Hybi 00, 07-17 draft specs (server only)
- Message/event based interface
- Supports secure WebSockets (TLS), IPv6, and explicit proxies.
- Flexible dependency management (C++11 Standard Library or Boost)
- Interchangeable network transport modules (raw, iostream, Asio, or custom)
- Portable/cross platform (Posix/Windows, 32/64bit, Intel/ARM/PPC)
- Thread-safe
