How lanqi1796-eng/cpp-reactor-http-server works

This is a learning-oriented C++17 HTTP/1.1 server. A client connection enters through the server’s listening socket; the EventLoop and Connection handle nonblocking I/O, the server parses and routes requests, then returns serialized responses. GET requests use static files; POST /echo is processed by a worker and handed back to the EventLoop for sending. The graph preserves the reactor, parsing, response, static-file, and worker-pool layers. Some links rely on README documentation because source excerpts omit wiring details.
