The http Protocol doesn't support such a thing. The continue-flag (-c)
depends on the
file-size only as you have implicitly mentioned. Rsync relies on
another rsync process on the other
side sending a "rolling checksum" over the contents of the file. Http
doesnÂ’t do such a thing.

The only thing I can recommend at this point is using rsync or not to
use the -c flag leading
to a download of the whole thing every time.
