I suspected so. However, there are also a lot of lines, where
%b is not equal to filesize (for example, for a 3Mb file, it can
be 1034567, 2065789, almost anything, and it's not 206 response,
but 200) - does it mean that server does not attempt to send the
whole file?

I haven't checked the algorithm. But it certainly may be a 2.0.49 bug
or it may be that the server is sending chunked-encoding and only
measuring the size of the chunks it attempts to send. In any case, %O
is the recommended way to track bandwidth used, not %b.


With Apache 1.3 %b was a good estimate of waht was actually sent
(I checked it then by downloading and cancelling transfers) - did
it changed with 2.0 ?

Yes, it changed in 2.0. It was never perfectly accurate in 1.3 either,
but it was closer to what someone wanting to measure bandwidth was
interested in.
