Question

I can’t get…

<?php
   header( "Refresh: 5; URL=http://www.mywebsite.com" );
?>

…working in Internet Explorer (damn you!).

It works great in Chrome and if I use…

header("Location: http://www.mywebsite.com");

…it works in both, but I get no delay.

Try including it as a meta tag, or reloading via JavaScript.

Meta tag:

<meta http-equiv="refresh" content="5;URL='http://example.com/'">

Javascript:

window.onload = new function() {
  setTimeout(function() {
    location.reload();
  }, 5000);
};
