For some reason, this doesn't seem to help. request.servervariables("http_referer") keeps referring to the same original form, even when you refresh the post form.
>You can check to see if the request.servervariables("http_referer") is the current page. If it is, then the form was posted to itself, if not, it was refreshed.
It's "my" world. You're just living in it.
