Hmm, maybe.  I like at least half of the section from your original 
link.  The use of mod_proxy (I think) allows you to do transparent 
redirection -- the visitor doesn't see the .nyud.net added to your 
hostname.  Of course, it occurs to me that your webserver ends up 
fetching the Coralized resource and serving it back to the client, 
right?  That's what mod_proxy does, I would assume, so I guess it's not 
really redirection at all.  So I don't really see the benefit; 
presumably there's something with the mod_cache bit that does something 
cool that I haven't thought of.

Anyhow, yeah, mod_rewrite would be the way to Coralize your site if it's 
getting hammered, though while you're using that method, site visitors 
will get a redirect to the .nyud.net address, which is less than ideal. 
  But I suppose it's hard to complain about free bandwidth ^_~.
