The webmaster is an idiot. The links should point to host.com and DNS rotation
should forward them to the mirrors.

You can replace the links but you're not going to be able get more files with
httrack.

Instead YOU, not the webmaster must perform the redirect.
get the mirror3.host.com IP address with the command line:
nslookup mirror3.host.com
Edit HOSTS file with notepad. Add two lines at the bottom
mirror3IPaddress mirror1.host.com
mirror3IPaddress mirror2.host.com

On XP and later the location is C:\WINDOWS\system32\drivers\etc\
