I agree, except there's one exception to this that I can't see a way around.
When dealing with form submissions the receiving file needs to validate all
the code before anything is sent to the browser, update the database (or
whatever) and then redirect to itself with some sort of GET flag that issues
a thankyou note or something.
Otherwise people can hit "refresh" and post the data twice, or 10 times :)
I can't see any SERVER SIDE way around this.
