Memcache question?

It seems that the server does not perform the active close normally in
the memcache environment.
If it is so,why ?

more detaily:
it will call ngx_http_upstream_process_non_buffered_downstream(r) for
sending response to the client and it seems that
the server does not perform the active close beween the client and
server.
