I need redirect with time delay, but to show the first website

Hi,
Let's say i own domain1.com, i want all the visitors that will enter this domain, will see the content of the whole site for 1 minute, then, automatically, regardless what content they are browsing in domain1, they will be redirected to domain2.com,

how can i do that?

appreciate if someone can help

Thank you

 

session_start();
if (!isset($_SESSION['minute']) {
$_SESSION['minute'] = time();
} else {
     $delay = time() - $_SESSION['minute'];
     if ($delay >= 60) {
          header("Location: http://www.yournewdomain.com");
     }
}

PHP:

 

<?php
header('Refresh: 60;url=http://www.domain2.com');
?>

PHP:

Edit: just realized not what you wanted, id go with the above example.

 

And what if he'll click on another link in his page ( let's say, another article ) ? It'll start to countdown from 0 again and again ..
