Golang写net.Dial响应浏览器

I am playing with the net package, and i want to make a simple proxy. First i make a listener on localhost, then i dial the remote address

remote, err := net.Dial("tcp", "google.com:80")
if err != nil {
    log.Fatal(err)
}
defer remote.Close()

fmt.Fprint(remote, "GET / HTTP/1.0

")

How can i pipe the response to the browser? Or do i need to work with the default webserver and copy the response body? I really want to try it with net package or something

thx

    To copy the connection from the remote is used 2 goroutines with io.Copy

    func copyContent(from, to net.Conn, done chan bool) {
        _, err := io.Copy(from, to)
        if err != nil {
            done <- true
        }
     done <- true
    }
    
    // in the main func
    done := make(chan bool, 2)
    go copyContent(conn, remote, done)
    go copyContent(remote, conn, done)
    <-done
    <-done
