validateProxyResponse only check status code and version

[isabelge]

Would it be possible to validate the proxy response with the status code and the version?
Some proxy response with connected and not connection established and in that case the validation false.
If it could be changed to something like this, it would also work for proxies with a different response.

@Override
public boolean validateProxyResponse(ProxyResponse response) {
    Objects.requireNonNull(response, "'response' cannot be null.");


    final HttpStatusLine status = response.getStatus();
    if (status == null) {
        logger.error("Response does not contain a status line. {}", response);
        return false;
    }

    return status.getStatusCode() == 200 && SUPPORTED_VERSIONS.contains(status.getProtocolVersion());
}
