I find this discussion very interesting, since redirecting is a subject that
comes up in just about every project I can remember. Also, I think I can
finally contribute my $0.02 to the list...

I'd like to point out that is usually safe practice to put an exit; line
after the header/Location call. I have been baffled by weird results more
than once, usually because something was echoed after the header call.

poor maintenance. What we call workability of the machine is just an
objectification of this peace of mind. The ultimate test is always your own
serenity." - Zen and the Art of Motorcycle Maintenance.
