[jira] [Commented] (HTTPCORE-684) Connection is unexpectedly closed with http1.1, TLS, old nginx

    [ https://issues.apache.org/jira/browse/HTTPCORE-684?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17409906#comment-17409906 ]

Commit 4bc58d4df935d43c5171d4c5174a180f2e78a739 in httpcomponents-core's branch refs/heads/HTTPCORE-684 from Oleg Kalnichevski
[ https://gitbox.apache.org/repos/asf?p=httpcomponents-core.git;h=4bc58d4 ]

HTTPCORE-684: async SSL i/o session fails to propagate end-of-stream events to the protocol handler. This can cause a failure in handling of identity transfer encoded HTTP/1.1 response messages

> Hello.
> We use AsyncHttpClient from Apache HttpClient5 (version 5.1).
> We faced an error when connection is unexpectedly closed using TLS, forced HTTP/1.1, and nginx version older 1.18.0.
> In the log below the server responds with 200 OK and an empty body.
> We can see response headers but connection is prematurely closed.

> That happens with the almost default configuration of the HTTP client (only versionPolicy and tlsStrategy are configured). 
> To reproduce such behavior all of these conditions must be met:
> 1) Server must be accessed via nginx version older 1.18.0 (I tested 1.16.1 and 1.18.0);
> 2) A request contains a body;
> 3) A response doesn't contain "Content-Length" header;
> 4) TLS is used.
> 5) HTTP/1.1 is used.
>  
> I think there is a bug. We've tried httpclient5 (classic, version 5.1) and AsyncHttpClient (Netty based). Both of them work correctly.
