我们在这里做了同样的事情来验证基于NTLM的代理。

We did the same here for authenticating on a NTLM based proxy.

代理上的身份验证实际上是正常的 HTTP基本身份验证。

The authentication on the proxy is actually a normal HTTP Basic Authentication.

我们使用以下方法：

protected URLConnection newURLConnection(URL pURL) throws IOException {
    URLConnection urlConnection = super.newURLConnection(pURL);

    String auth = new String(Base64.base64Encode(new String("username:password").getBytes()));
    auth = "Basic " + auth;
    urlConnection.setRequestProperty("Proxy-Connection","Keep-Alive");
    urlConnection.setRequestProperty("Proxy-Authorization",auth);
    return urlConnection;
}

这与代理jvm设置一起完成了这个伎俩。

That, together with the proxy jvm settings, did the trick.
