[I know this topic died out about a month ago, but I'm catching up after a
vacation (1260 e-mail messages were patiently waiting for me!)]

I also think alternate anchor targets is good idea (which is why I made a
similar suggestion to this group 2 months ago).

I'd like to make the point that this ought to be implemented in HTML,
independent of HTTP. Consider that an HREF attribute can use "file:" to
refer to a document that's not hosted on the Internet [1]. For example, if I
have a body of HTML documents on a CD-ROM, I would like to be able to
give Internet addresses as the primary targets and CD-ROM filenames as
the secondary targets. Other proposals for HTTP-level support of
caching and mirroring don't seem to take this into account. Netscape's
really lame caching scheme doesn't work for anything like this either.
Dan's suggestion, on the other hand, works great, as long as there is a
mechanism for indicating priority (even for groups of links, so you could
say "if you don't find it here first, try one of these other four places next,
then try this place") .

Complete functionality would need to include (at minimum) support for the
following options:
- timeout
- author-specified priority (including groups of URLS)
- modification-date priority
