It's not a connection. It's a series of data-packets sent using TCP/IP.
The large file is chopped into many packets that are sent by (possibly)
various routes and may arrive out-of-order or may need to be re-sent (if
some get lost).

The best you can hope for is "while the server is serving the request".
You could set a flag when the request is received and clear it when the
log is written (the log is only written at the end of the request).

a module may be able to hook into the state variables you'd need to
check to see this but it would not be trivial - you'd be into semaphores
and stuff like that...
