FreePBX mirrors do not support wget --continue i.e. HTTP "Range" header

For example:

wget -c http://mirror.freepbx.org/modules/packages/freepbx/freepbx-14.0-latest.tgz

does NOT pick up a download where it previously failed, it returns to the beginning to start again. In the same way, if wget restarts automatically due to a network-caused failure (e.g. Read error, Connection closed, ...) it does not continue but restarts the download from zero.

FreePBX is used in many locations where Internet service is unreliable and thus the above behavior is very frustrating and wastes both time and (expensive) per-Gb Internet charges.

As an alternative, the --continue feature would work with an FTP server, but the above URL works only with http, not ftp. My web searches did not reveal an ftp site from which FreePBX 14 can be downloaded. Sometimes older technology is better...
