Lighttpd

I'm running 1.4.19-0ubuntu3 on Ubuntu 8.04. It looks like "%X" in accesslog.format doesn't show "X" for aborted transfers. For example, if I add

accesslog.format = "%h V %u %t \"%r\" %>s %b \"{Referer}i\" \"%{User-Agent}i\" \"%{Content-Length}o\" %X"

to my configuration, then start a transfer using wget and hit ^C before it's finished, the following shows up in the access log:

x.y.z.q media-2.cacetech.com - [06/Feb/2009:14:11:37 0800] "GET /wireshark/prerelease/WiresharkPortable-0.99.8pre1.paf.exe HTTP/1.0" 200 880321 "" "Wget/1.11.4" "17021795" +

The transfer clearly didn't finish (880321 << 17021795). Shouldn't there be an "X" at the end of the log file entry?

Is there any other way to signal an aborted transfer in the log file? Right now, AWStats is inflating my download stats and I'd rather have accurate numbers.
