Interesting, I had not thought of putting the flag variable in the main
flowscript function.
Although one advantage of the redirect is that the user can refresh
smoothly, without any warning message. In some browsers, when you
refresh a page that was gotten through a POST, you get an alert about
resending the form data.
And what happens when he uses the browser's back button? Don't you end
up executing the db operations again? That's why I don't like that
"pattern". It fixes one particular symptom but not the actual issue. IMO
only invalidating the continuation helps. But then I wonder how one
could claim "continuations are fixing the browser's back button" since
you actually disable it. I might overlook something but it seems both
can't address the issue completely.
