nginx isn't forward proxy, and it know nothing about 
Proxy-Connection.  If server you are connecting to happens to keep 
connection alive due to "Proxy-Connection: keep-alive" header - 
the behaviour you see is quite expected.

You have to manually remove this header from request via something 
like

    proxy_set_header Proxy-Connection "";

Or, much better, just don't use nginx as forward proxy.
