I would expect (and looking briefly at the code this appears to be true)
that an http_stats event is generated whenever an HTTP connection finishes,
even if nothing happened during the connection (no GET request, just a
SYN handshake).  If so, then it would make sense that such unproductive
sessions have $num_requests equal to 0.

I'm not following this comment ...
