> Key: HTTPCLIENT-1833
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1833
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Affects Versions: 4.5.3
> Environment: Client: Windows 8.1, Proxy: Squid 3.5.20 on Centos 7.0
> Reporter: Antony Helliwell
> Assignee: Karl Wright
>
> We have a test setup using Squid 3.5.20 as an authenticating proxy configured with NEGOTIATE+NTLM. When attempting to connect to a target host we get the following traceback:
> java.lang.RuntimeException: Unexpected token

> I've tracked this down to WindowsNegotiateScheme using the SPN HTTP/<target host name> to authenticate with the proxy rather than the SPN HTTP/<proxy host name>.
> Applying https://github.com/apache/httpclient/pull/28 fixes the problem.
> The request is from early 2015 and doesn't seem to have been applied due to a pending rewrite, however the bug still exists at 4.5.3.
