# Non-parsed headers CGI 1.1 error script in Perl to handle error requests
# from NCSA HTTPd 1.4 via ErrorDocument. This should handle all errors in
# almost the same fashion as NCSA HTTPd 1.4 would internally.
#
# This script is in the Public Domain. NCSA and the author offer no
# guaruntee's nor claim any responsibility for it. That's as pseudo-legalise
# as I get.
#
# This script doesn't do any encryption or authentication, nor does it
# contain hooks to do so.
#
# This was written for Perl 4.016. I've heard rumours about it working with
# other versions, but I'm no Perl hacker, so how would I know?
