Yes, this is a bug; apache should return 301.
I've tried chimera, netscape, mosaic and lynx, and none of them treat 301
any differently to 302.

chimera, netscape and mosaic do not cache a redirection, even if it is
a 301 redirect. Reloading the original document (without the trailing '/')
causes them to reissue a GET for that document.

lynx _always_ caches a redirection, even if it is a 302 redirect.

I think we should change the apache behaviour; hopefully some browsers may
follow suit. I have a patch for 0.6.5.
