I suggest that a redirector be allowed to return more than one
URL, and that URLs known (or, for that matter, host names known - this
solves the problem of netscape/lynx/et al not doing multiple hostnames
when going through a proxy) to be in the database (positively cached)
be used first, then ones from cache digests, then whichever one gets
responses from other caches, then finally try them at the origin
server(s) in order of the return from the redirector.
