An unusual dns question

[mcmanus at ducksong.com (Patrick R. McManus)]

is it possible that there was once an HTTP redirect (3xx HTTP response
code) at http://listman.redhat.com that pushed traffic to
https://listman.redhat.com.. and your old copy of netscape has that [no
longer existant] redirect cached?
