Hlaska „Please click here to continue“

Pratele prosim poradte. Nektere deletrvajici skripty se ukonci vykreslenim stranky s hlaskou „Please click here to continue“. Nechapu proc.

Nasel jsem v Nette\Http\Response toto:

<?php
	public function redirect($url, $code = self::S302_FOUND)
	{
		$this->setCode($code);
		$this->setHeader('Location', $url);
		if (preg_match('#^https?:|^\s*+[a-z0-9+.-]*+[^:]#i', $url)) {
			$escapedUrl = htmlspecialchars($url, ENT_IGNORE | ENT_QUOTES, 'UTF-8');
			echo "<h1>Redirect</h1>\n\n<p><a href=\"$escapedUrl\">Please click here to continue</a>.</p>";
		}
	}
?>

Diky.
