e.g. to re-direct accesses to everything at http://www.apache.org/
to an appropriate mirror site, you would want to put something like
this in your server config
RedirectDomain / http://Bond.edu.au/External/Misc/apache/ .au .nz
.jp .kr .cn
RedirectDomain / http://iuinfo.tuwien.ac.at/apache/ .at .de .dk
RedirectDomain / http://sunsite.mff.cuni.cz/web/apache/ .cz
RedirectDomain / http://sunsite.icm.edu.pl/pub/www/apache/ .pl
RedirectDomain / http://sunsite.doc.ic.ac.uk/packages/apache/ .uk
.fr .be
(etc...!)
If nobody else is working on this sort of thing, I might have a
stab at hacking this into the NCSA and Apache servers
Cheerio,
