Answer 1

Since an iframe makes a GET request there isn’t really any way to distinguish a GET request coming from the browser itself and one coming from an iframe embedded in a page. In both cases the browser makes the same GET request. You could probably write some JavaScript code in your “iframe” page that detects whether or not it is loaded in the top window and redirects if it isn’t.

From the accepted answer on How to identify if a webpage is being loaded inside an iframe or directly into the browser window?

using the window properties top and self

<script type="text/javascript">
    if (top === self) {
        location = '/index.php';
    }
</script>
