shelf_proxy is a Shelf handler that proxies requests to an external
server. It can be served directly and used as a proxy server, or it can be
mounted within a larger application to proxy only certain URLs.

shelf_io.serve(proxyHandler("https://www.dartlang.org"), 'localhost', 8080)
.then((server) {
print('Proxying at http://${server.address.host}:${server.port}');
