Perhaps this is what you mean?

Disclaimer: I have not tried compiling or running any of this

public void doGet(HttpServletRequest request, HttpServletResponse response) {
    URL url = new URL("http://your-other-server/the/resource/you/want");

    InputStream source = url.openStream();
    OutputStream destination = response.getOutputStream();

    byte[] buffer = new byte[1024];
    int length;
    while ((length = source.read(buffer)) != -1) {
        destination.write(buffer, 0, length);
    }

    source.close();
}
