Setting remote ip and port in littleproxy

In littleProxy, how can I set the remote ip and port? The sample in their website :

HttpProxyServer server =
    DefaultHttpProxyServer.bootstrap()
        .withPort(8080)
        .start();

only sets the local port.

The request target must be in absolute-form, as specified by RFC 7230, section 5.3.2, to be forwarded by LittleProxy. The following code works in LittleProxy v1.1.0beta1:

Pattern REQUEST_TARGET_ORIGIN_FORM_PREFIX = Pattern.compile("/[^/]");

@Override
public HttpResponse clientToProxyRequest(HttpObject httpObject) {
  if (httpObject instanceof HttpRequest) {
    HttpRequest httpRequest = (HttpRequest) httpObject;
    if (REQUEST_TARGET_ORIGIN_FORM_PREFIX.matcher(httpRequest.getUri()).lookingAt()) {
      String uriRemote = "http://myRemoteHost:myRemotePort" + httpRequest.getUri();
      httpRequest.setUri(uriRemote);
    }
  }
  return null;
}
