I would tend to agree, but I've seen this several times with
transfers from different sites. If the 'trend' is for network devices to
prefer web transfers, then obviously it would make sense to use them rather
than ftp. I guess it would be nice to see it from a single machine (i.e. one
that is running both the http and ftp servers) and from a reasonably known
site (i.e. where the network topology is known).
