Well, the more persistent URIs the better, so both.

The question isn't very clear.

There are distinct HTTP redirection codes for "don't use
this URI any more; use that other one from now on" (301)
and "keep using this URI, but for now, look over there
for what you're after" (302).


So if you're trying to be good about persistent URIs,
but the world changes and you have to react, putting
up a 301 for 18 months or so seems like a reasonable

Mark Baker and I proposed 3 years, actually, when
we wrote up something related...
