// Simple HTTP server example (for illustration purposes only).
// This shows how a plaintext TCP/IP connection is accepted to then receive an
// application level protocol message (HTTP request) and reply with an
// application level protocol message (HTTP response) in return.
//
// This example exists for illustraion purposes only. It does not actually
// parse incoming HTTP requests, so you can actually send *anything* and will
// still respond with a valid HTTP response.
// Real applications should use react/http instead!
//
// Just start this server and send a request to it:
//
// $ php examples/03-http-server.php 127.0.0.1:8000
// $ curl -v http://localhost:8000/
// $ ab -n1000 -c10 http://localhost:8000/
// $ docker run -it --rm --net=host jordi/ab -n1000 -c10 http://localhost:8000/
//
// You can also run a secure HTTPS echo server like this:
//
// $ php examples/03-http-server.php tls://127.0.0.1:8000 examples/localhost.pem
// $ curl -v --insecure https://localhost:8000/
// $ ab -n1000 -c10 https://localhost:8000/
// $ docker run -it --rm --net=host jordi/ab -n1000 -c10 https://localhost:8000/
//
// You can also run a Unix domain socket (UDS) server like this:
//
// $ php examples/03-http-server.php unix:///tmp/server.sock
// $ nc -U /tmp/server.sock
//
// You can also use systemd socket activation and listen on an inherited file descriptor:
//
// $ systemd-socket-activate -l 8000 php examples/03-http-server.php php://fd/3
// $ curl -v --insecure https://localhost:8000/
// $ ab -n1000 -c10 https://localhost:8000/
// $ docker run -it --rm --net=host jordi/ab -n1000 -c10 https://localhost:8000/
