I think there's a minor mistake: "The program does not continue until the remote end receives the corresponding HTTP response. In the initial browser.go call, for example, the remote end will only send its response once the browser has finished loading the requested page." I think this should read "until the remote end SENDS the corresponding HTTP response", or "until the LOCAL end receives the corresponding HTTP response."
