#
# FetchURL downloading a file from a LightTPD server through a Wireguard VPN
#
# By default, the file is an short inline HTML file at lighttpd and downloaded
# into RAM in fetchurl. However, when the test is run with base-linux,
# lighttpd uses a file created by the host filled filled with zeroes and of
# customizable size and fetchurl downloads into the host FS, so the test can
# then check the MD5 sum of the file.
