This section allows user to change the HTTP port via HTTP. As long as pressing Apply, the web
daemon will restart the new configuration, and you won’t see the response at the web browser.
We need a way to reply immediately and apply the configuration latter. By using fork, we can
make parent process reply immediately and the child process execute the configuration.
Note: Remember close the file descriptor stdin and stdout within the child process context.
