NLTM auth using HttpUrlConnection failing

问题 I am trying to authenticate against a server supporting NTLM authentication in my Java application using java.net's HttpUrlConnection. The problem is that the application fails to send the Authenticate response. I have attached proxy to the http connection so that the traffic is routed via fiddler. In fiddler i can see Negotiate message being sent, and server Challenge is received. But after this, the application just stops saying it got a 401, without sending the type3 authenticate message.

问题 this is my first question, so please, bear with me. I have a Swing application, which gets data in a for of XML from a server through HttpURLConnection.

In some question's comment I read that it would be better to use Apache HttpClient instead of HttpURLConnection to maintain a live

由 强颜欢笑 提交于 2019-12-07 04:08:23
问题 This question already has answers here : HttpURLConnection.getResponseCode() throws IOException when code is known (2 answers) Closed 3 years ago . I can see that getResponseCode() method is just a getter Method that returns the statusCode already set by the a connect action that happened before.

问题 We have a java client side application deployed in our customer (a java application, not an applet).
