Eventually it ends up in ZnUtils streamFrom:to:size: with an empty totalSize (as content-length is unset) and then produces an empty file. However the download works fine if I simply do an upToEnd on the ZnChunkedReadStream. This can be seen by executing ZnClient new url: 'http://www.google.com'; downloadTo: '/tmp/foo.txt'.

Yes, this seems to be a problem: your analysis is correct, since the size is unknown upfront - the whole idea of chunked transfer -, #streamFrom:to:size: in its current version cannot work. I will look at this tomorrow, I am pretty sure this can quite easily be fixed (minus the progress bar).

Thanks for reporting this.
