Subject unresolved internal redirect bug
Date Mon, 18 Nov 1996 03:14:16 GMT
I consider this to be a showstopper bug because it hides bad things
from being seen, prevents 401 redirects from working, and possibly
other things which would be really hard for a user to diagnose.
At the least, I'd like someone familiar with internal redirects to say
why it isn't a showstopper bug, since it is giving me the heebie-geebies.
