how to stop the connection when there is no request and no data response exceeds a certain time?

// proxy is used to suffle data from src to destination, and sends errors
// down a dedicated channel
func proxy(dst io.Writer, src io.Reader, errCh chan error) {
_, err := io.Copy(dst, src)
if tcpConn, ok := dst.(closeWriter); ok {
tcpConn.CloseWrite()
}
errCh <- err
}
