URNs, Mirror sites, and Squid
Very cool - I think I'm going to set something like this up.

Yup, this is what we did; ties in nicey into the proxyserver as a separat
module. THe only catch is that the BIND version you link it against needs
NAPTR and SRV support.

That's no good. I have no proxies, knowledgeable or otherwise, between
me and anything.
Cheers,
Ben.

Atually, due to the way URNs work, it as perfectly possible to 'hide' the
URN's behind the webserve wehn a not URN aware client/proxy comes a long
to fetch; i.e. the entire resolution is done by the last knowledgable
prxoxy.

Nifty.
But things are not as cool as they could be. Click on a URN in Netscape,
and it tells you to use a proxy for URN support. We ought to be able to
build this into Apache, but if the browsers won't send a URN request,
we're stuffed. Sigh.
Cheers,
Ben.

Brian,
As one of the URN folks and as one of the earliest implementors, feel free
to ask for any help; we have lots of scripts, libraries and the lot here
at ceo, as most our web systems are based on URN tech. Be aware though
that thee is still some controversy (or technical trouble) when it comes
to the actual resolution step. And I also think that not everyone in the
URN working group is completely thrilled by some of the syntax choises and
scaling aspects of what sometimes is called an URN, but behaves more tlike
a URL on steroids.
What is it you had in mind ?
