Hello,

I am using libmicrohttpd with MHD_OPTION_NOTIFY_CONNECTION parameter to
receive notifications for TCP connection opening/closing. Notifications for
opening case are coming through as expected, however I am experiencing
problems with closing case, where I am NOT getting the callback when my
client terminates, though I can see client FIN packet in tcpdump on the
server side and connection stops appearing in netstat.

Eventually the closing notification is being delivered by libmicrohttpd but
that is just after a new TCP connection is opened. The sequence of
callbacks I am seeing is as followed:

1) callback with MHD_CONNECTION_NOTIFY_STARTED - TCP connection  A opened
2) callback with MHD_CONNECTION_NOTIFY_STARTED - new TCP connection B is
opened
3)  callback with MHD_CONNECTION_NOTIFY_CLOSED - TCP connection  A closed

Of course I would expect nr 3 to come before nr 2. I am using nc to
open/close sockets on client end.

I would appreciate any comments on the described issue. Is that behavior
correct? If not is there a way to make it right?

Kind regards,
Daniel
