112 Nginx does not obey client http version Jiri Lunacek somebody "Hi.
I have discovered that nginx 1.0.12 does not obey client HTTP protocol version and sends a reply always in version 1.1.
In our situation this caused a proxy sending out stripe headers with the reply to client.
Client -> nginx proxy http/1.0 -> nginx server http/1.1 striped reply -> nginx proxy http/1.0 expecting only data but receiving also stripe headers.
This is a communication log with nginx 1.0.12 in default configuration:
