Re: Best way to cache mirror sites

Using a redirector you can use a regex expression to change a url to
another. Thus cdrom.com is mirrored in sa by is.co.za/cdrom we redirect all
traffic to cdrom.com to is's mirror.

http://www.elab.co.za/squirm/

is the redirector I use they've got some examples on there too.
