Can you present a sample web page that exercises the doubling phenomena?

Search results in google return some interesting discussions, one of
them being about JavaScript problems, another about multipart forms.

I can think of two ugly things you can do to fix it without touching any
existing forms.  Neither of them is a good solution, hopefully you will
get some better ones.

1) You could probably write a "forward" app, which just discards the
same submission, from the same host, within the a given timeframe, but
forwards everything else to whatever form it was destined for. Not very
pretty.  

2) If you tag submissions with some kind of ticket, then you could do
something similar but discard duplicate tickets.  Not a great answer
either.

Obviously, the best thing to do to ensure against this kind of double
entry would be to give each request a unique id, and keep state.
