Hmm... I tried this function, but it doesn't seem to behave any
differently than using 'open.

REBOL[
Title: "Redirecting HTTP to FTP"
Author: "Romano Paolo Tenca"
Version: 1.0.0
Date: 29/06/01
Purpose: {
Try a http url
if fail for error 800 (redirect to a ftp site)
return a custom object (redir)
with info for the ftp
Perhaps worked better if it was an object
with a public routine embedded but it is
my first Rebol routine
