note 52009 added to function.header

Can anyone tell me how I can add this <code><?php // Date in the past header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // always modified header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); // HTTP/1.1 header("Cache-Control: no-store, no-cache, must-revalidate"); header("Cache-Control: post-check=0, pre-check=0", false); // HTTP/1.0 header("Pragma: no-cache"); ?> <code> to my site here: http://hovedogs.co.uk/cubecart I seem to have stopped the front page from caching, but when users click on an image in a category it is caching?
