Oleg Kalnichevski updated HTTPCLIENT-1340:
------------------------------------------
Summary: Connection re-used in a inconsistent state despite 'Connection:
close' after successful authentication (was: ProtocolException when
Connection:close response header is present)
> Connection re-used in a inconsistent state despite 'Connection: close' after
> successful authentication
> -------------------------------------------------------------------------------------------------------
>
> Key: HTTPCLIENT-1340
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1340
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Affects Versions: 4.2.4, 4.3 Beta1
> Reporter: Igor Fedorenko
> Priority: Critical
> Fix For: 4.2.5, 4.3 Beta2
>
> Attachments: hc4.log, HTTPCLIENT1340.java
>
>
> The problem was originally observed when using maven 3.0.5 and newer with
> maven repositories served by nginx that has username/password authentication
> and connection keep-alive enabled.
> I was able to reproduce the problem using standalone test application that
> executes the same HttpGet request in a loop. Below is wire log of the last
> two iterations that lead to "ProtocolException: The server failed to respond
> with a valid HTTP response". From the log the client apparently stopped
> processing of the response with Connection:close heaader and then reused the
> connection for the next request.
