There is an issue with gzipping and ranges - what should be done first.
As far as I know there is no order description in RFC (correct me, if
I wrong), so we can implement only de facto state (as it's already
done with gzip content encoding).
Apache (at least 2.3.8) gzips content first and then process ranges
on gzipped body and according gzipped content length, but I do not
know how browsers handle this.
