$sent_* refers to things sent to the client.

http://nginx.org/en/docs/http/ngx_http_core_module.html#variables

$upstream_* refers to things received from the upstream.

http://nginx.org/en/docs/http/ngx_http_upstream_module.html#variables

That means that it won't be sent to the client, so the $sent_* variable
should be empty.
