------------------------------------------
Summary: Proxy authentication Error - NTLM authentication error:
Unexpected state: MSG_TYPE3_GENERATED in Http Client 4.3.1
Key: HTTPCLIENT-1446
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1446
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpClient
Affects Versions: 4.3.1
Environment: Windows 7
Reporter: Carina Lansing
We are using httpclient 4.3.1, trying to connect to a website that requires
basic authentication through an NTLM v2 proxy. It appears that the proxy
authentication is successfully negotiated, but then when trying to process the
challenge from the target web site in the next pass, the NTLMScheme is throwing
this exception at line 147? We are instantiating our http client via the
snippet shown below. Attached is a debug trace of the HttpGet operation.
