Volleyが勝手にリダイレクトするのを禁止する方法

public class MyHurlStack extends HurlStack {

    @Override
    protected HttpURLConnection createConnection(URL url) throws IOException {
        HttpURLConnection connection = super.createConnection(url);

        // 自動リダイレクトを禁止する
        connection.setInstanceFollowRedirects(false);
        connection.setRequestProperty("Accept-Encoding", "");

        return connection;
    }

    @Override
    public HttpResponse performRequest(Request<?> request,
            Map<String, String> additionalHeaders) throws IOException,
            AuthFailureError {
        URL url = new URL(request.getUrl());
        if (url.getHost().equals("開発環境のホスト名")) {
            // Basic認証ヘッダの追加
            additionalHeaders
                    .put("Authorization", "Basic ********************");
        }

        return super.performRequest(request, additionalHeaders);
    }

}
