Hello, We have a bug report in JMeter : https://bz.apache.org/bugzilla/show_bug.cgi?id=58583
To summarize, setting "Connection: close" header in the requests does not make HttpClient close the connection on the client side. It seems to be a violation of RFC 2616: http://tools.ietf.org/html/rfc2616#page-45 http://tools.ietf.org/html/rfc2616#section-14.10 And RFC7230: http://tools.ietf.org/html/rfc7230#section-6.1 I am not sure what to think about this. Regards Philippe
