No. post_handler (the second argument of
ngx_http_read_client_request_body) should be called when the body will be
successfully received.

ngx_http_finalize_request does not close the connection whenever rc ==
NGX_AGAIN. Instead ngx_http_read_client_request_body sets read handler to
ngx_http_read_client_request_body_handler. Therefore the read handler will
be recalled, not your handler.
