function authenticate() {

header('WWW-Authenticate: Basic realm="Test Authentication System"');

header('HTTP/1.0 401 Unauthorized');

echo "You must enter a valid login ID and password to access this resource\n";

exit;

}

if (!isset($_SERVER['PHP_AUTH_USER']) ||

($_POST['SeenBefore'] == 1 && $_POST['OldAuth'] == $_SERVER['PHP_AUTH_USER'])) {

authenticate();

}

else {

echo "<p>Welcome: {$_SERVER['PHP_AUTH_USER']}<br>";

echo "Old: {$_REQUEST['OldAuth']}";

echo "<form action={$_SERVER['PHP_SELF]}' METHOD='POST'>\n";

echo "<input type='hidden' name='SeenBefore' value='1'>\n";

echo "<input type='hidden' name='OldAuth' value='{$_SERVER['PHP_AUTH_USER']}'>\n";

echo "<input type='submit' value='Re Authenticate'>\n";

echo "</form></p>\n";
