What I sometimes do is redirect the user to the returned page after doing what is suppose to be posted. But I am sure there is a better solution. Interested in knowing what.

Hes worried about someone refreshing and being able to resubmit the post. I do not think unsetting them will work, but I haven't ever tried it either.

Doing a redirect is pretty standard actually. However, you could also do a duplicate record query before committing the insert. There is no state in HTTP, you can't just clear POST.
