setcookie is a header function, which means it has to be called before any output is generated. Easiest way to solve this is to move the ob_start() to the beginning of your code.
good luck.

thanks, but that doesnt leave a cookie, or maybe my script to check for the cookie is wrong:
Code:
<?php
if ($_COOKIE[auth] == "ok") {
echo "You are now on page one.";
} else {
echo "You are not logged in, please do so.";
include("show_login.html");
}
?>
