Simon Zhu commented on NUTCH-1086: ---------------------------------- Hi Talat/Julien/Markus, I tested NTCredentials in components httpclient 4.3.4 by using a proxy server that requires NTLM authentication, and the response code was 200 OK, However when used NTCredentials of commons httpclient 3.1, which is currently used by protocol-httpclient, the returned code was 407, indicated the proxy server I'am using found NTCredentials in httpclient 3.1 could not explain NTLM protocol correctly. I supposed the reason is commons httpclient 3.1 was EOL in 2007 but the current NTLM version was released in 2008. Since httpclient 4.x does not compatible with 3.1, so IMHO it's not easy to address the NTLM authentication issue by adding a patch. But will be very happy if anyone can help to develop such a patch for the issue. Appreciate all kinds of advice/suggestions/clues for the proxy server authentication issue, more than happy to have further discussions on this.
