Thanks as ever for a great response and new ideas.
I did as Douglas suggested and reloaded the page with a GET which I
could test for. It also provided a thank you page which can then be
refreshed with no repercussions as Peter advised.
BTW its not about not being bothered but finding elegant solutions.
My thanks to a great group once again.
