	Some time ago I have used the following at ftp.linux.cz:

RedirectMatch (.*.iso)$ ftp://ftp.linux.cz$1

But now I serve the ISO images directly over HTTP. Just keep the following
two problems in mind:

1) ISO downloads tend to take a lot of time, and occasionally the MaxClients
	limit can be reached. In order to prevent the HTTP server which serves
	the FTP archive influencing the other virtual HTTP sites, it should
	be a separate Apache instance (not only a separate <VirtualHost>).

2) Make sure EnableSendfile is on (but beware that it does not work with files
	on a NFS volume (which I don't have) and it of course does not work
	over HTTPS.

Please don't top post and in particular don't attach entire digests to your
