Are you serious?  You'd download the 400MB zip file twice - once
just for measuring, and then again for the contents?

Are you sure, you cannot cache it locally on disk?
Are you sure you cannot request some kind of digest first,
that would just have nr of files and maybe total uncompressed
size?

Do you expect the download to be faster than saving the extracted
files on disk?
