Stop user to Shift+F5 on the Page
<p>Does any one here know how can I stop user to Shift+F5 or F5 (refresh the page) on the Page by Jacascript or jQuery?</p>

<p>The reason is just to stop the page resubmit the same variable into the server side after the user clicked on the 'submit' button then pressed F5 again</p>
