Hi,

What I mention is the header in response from backend server. Your answer about proxy_set_header is the "Connection" header in request.

Thanks

you mean something like this?
http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_set_header
  If the value of a header field is an empty string then this field will 
not be passed to a proxied server:
    proxy_set_header Connection "";
