Tobias Oberlies commented on HTTPCLIENT-1188:
---------------------------------------------
bq. If for whatever reason you cannot use the 'expect-continue' handshaking to
avoid this problem, ...
This is e.g. the case if the server is a Tomcat: see

> HTTP client does not monitor connection for error status while sending
> request body
> -----------------------------------------------------------------------------------
>
> Key: HTTPCLIENT-1188
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1188
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient
> Affects Versions: 4.1.3
> Reporter: Benjamin Bentmann
>
> Quoting from http://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html#sec8.2.2:
> bq. An HTTP/1.1 (or later) client sending a message-body SHOULD monitor the
> network connection for an error status while it is transmitting the request.
> If the client sees an error status, it SHOULD immediately cease transmitting
> the body. If the body is being sent using a "chunked" encoding (section 3.6),
> a zero length chunk and empty trailer MAY be used to prematurely mark the end
> of the message. If the body was preceded by a Content-Length header, the
> client MUST close the connection.
> This is apparently not the case with the HttpClient. While uploading large
> files (tens of MBs) whose transfer takes notable time (~ 30 sec) we observed
> the following exceptions (the variation in detail msg are either due to Java
> version or OS):
> {noformat}

> The cause for those is apparently that the server sends an error response
> before fully consuming the request body sent by the client. The server
> eventually closes the TCP connection (after having notified the client via
> FIN and RST) but the client continues to upload and runs into the closed
> server side.
