1211	nginx doesn't forward response body to client when scgi backend doesn't read all input	Joern Heissler		"I wrote a backend application with SCGI connection.
My client tries to POST a huge body, but my application doesn't like it.
It only reads part of the request, determines that it's too large, sends an error response and closes the connection. Nginx (according to strace) receives the full response.

The client receives the http response header, but the body (which according to the headers is Chunked) is completely missing. nginx just closes the connection.

Same behaviour on Debian/Sid with debian's nginx version, and Ubuntu Xenial with nginx' package from https://nginx.org/en/linux_packages.html"	defect	closed	minor		nginx-core	1.10.x	duplicate	scgi		"Linux joerntop 4.9.0-1-amd64 #1 SMP Debian 4.9.2-2 (2017-01-12) x86_64 GNU/Linux
