does nginx support linger_close as client? (no replies)

Hi guys
i run nginx as a proxy, it became a client when connecting to a upstream server.
i want to close the connection with SO_LINGER option when i read the full data, because linger_close send RST to upstream server and avoid too many time_wait state.
does nginx support the feature? (i think this feature is different with the existing lingering_clise directive)
