re-submit form on page reload

I have a simple JSF form (UIForm). the values from it are inserted into DB by link action (submit) . after that the page reloads and the form fields are filled.

if I reload the page by "reload" button in the browser or F5 the form submits once more and the values are inserted into DB again.

- How can I turn off my action when the form re-submits?

- Or how can I disable post back to my form after action?

Thanks.
