It could really be a site sucker. It first establishes connection pools and distributes requests for objects found in pages across these pre- established connections, then sends the reqeust and shutdown(SHUT_WR). It is also possible that there is a high packet loss rate on the client and that it took 7 seconds for it to manage to send its request after establishing the connection! That could also be the consequence of a bot saturating the client's link with many such requests.
