HTTP Body size calculation

[sebb <se...@gmail.com>]

I was just about to raise a bug against HC4, because the displayed
body size does not agree with the size of the downloaded file.

However, I suddenly realised that HC4 is measuring bytes received from
the wire, whereas Java and HC3 currently measure the end-user bytes,
i.e. after de-chunking.

We can just document this behaviour.

Or maybe we need to have yet another statistic for HTTP samples which
identifies the transport overhead?
Might be possible to measure this for HC3.1; I doubt it's possible for
the Java implementation.

No I don't think.
HC4 has the good statistic (the real stat), and I suppose that Java and
HC3 will become obsolete in the future.
JMeter should change the default http implementation to HC4 (or HC3 for
a transitional phase to HC4). HC is theorically better than the Java
implementation.
