If you want to add a specific page like you want to add a front page which only call when the front page is active.
To do so you can use this technique. Copy your page.tpl.php file and rename it as page–front.tpl.php and edit it.
So this page is call when any one click the front page.
In this way we can create a specific page just “–pagename”
