// HTTP server example. This server serves both static and dynamic content.
// It opens two ports: plain HTTP on port 8000 and HTTP on port 8443.
// It implements the following endpoints:
//    /api/stats - respond with free-formatted stats on current connections
//    /api/f2/:id - wildcard example, respond with JSON string {"result": "URI"}
//    any other URI serves static files from s_root_dir
//
// To enable SSL/TLS (using self-signed certificates in PEM files),
//    1. make SSL=OPENSSL or make SSL=MBEDTLS
//    2. curl -k https://127.0.0.1:8443
