java - 未找到 HttpClient 间歇性页面

Question

我使用以下代码并多次运行该方法，有几次我在 GZIP 中得到了我所期望的响应，而其他几次我得到了完全不同的响应（未找到非 GZIP 页面）。但是，如果我使用 Mozilla 或 IE 多次下载相同的 URL，我始终会得到相同的 GZIP 响应。

这是我尝试访问的服务器的错误，还是我需要设置任何参数以获得一致的响应？

我要下载的网址如下，你能告诉我吗？

public static byte[] dowloadURL(URL urlToDownload) {

    InputStream iStream = null;
    byte[] urlBytes = null;

    try {

        //HttpClient httpClient = new HttpClient();
        org.apache.http.client.
        HttpClient httpClient = new DefaultHttpClient();


        HttpGet httpget = new HttpGet(urlToDownload.toString());

        HttpResponse response  = httpClient.execute(httpget);

        iStream = response.getEntity().getContent();

        urlBytes = IOUtils.toByteArray(iStream);
        String responseString = new String(urlBytes);
        System.out.println(" >>> The response  string for " +urlToDownload.toString()+  " is "   +responseString);

    } catch (IOException e) {
        System.err.printf("Failed while reading bytes from %s: %s",
                urlToDownload.toExternalForm(), e.getMessage());
        e.printStackTrace();
        // Perform any other exception handling that's appropriate.
    } finally {
        if (iStream != null) {
            try {
                iStream.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }

    return urlBytes;
}
