How can i disallow indexing of one page only using meta tags if the script uses a global header?

Thanks :)

robots.txt or
<? if($_SERVER['REQUEST_URI'] == "/blah/blah.html") { ?>
<meta name="robots" content="noindex">
<? } ?>

do
<? echo $_SERVER['REQUEST_URI']; ?> to get the value for the page you are on.

cheers :)
