[solved] How to know if certain page is open

Is is possible to get to know if certain page is open (for example root, about) and by using if this page is root clause, then I would add extra blocks to my fe_page template.

Code:

---

<?php if ($this-> Page is Root): ?>
  <div id="banner">
  </div>         
<?php endif; ?>

---

I know that it is possible to create different layouts for different pages and then assign different fe_page layouts, but it would save me time and I can assign everything in one fe_page layout page.

Thank you in advance.

You can use this extension to easily handle different page wide content on hand selected pages.
