The page code itself can help you solve the problem. There you'll see the JS for you to use as a basis for your application.

here is the download URL: 

function download() {
url = QueryString("url")
// Remove o "http://" caso exista (apenas para não colocar duas vezes)
url = url.replace("http://", "")
// Adciona o "http://"
url = "http://" + url
top.document.location = url
}
</script>

Analyze counter code 

<script language="JavaScript">
//<![CDATA[
var xtx=20;
function IniciaRegressivo() {
if (xtx > 0) {
document.getElementById('botao').innerHTML = '<div class="protetor-botao"><a>Aguarde '+ 
x +' segundos</a></div>';
xtx = xtx - 1;
setTimeout("IniciaRegressivo();", 1000);
} else {
document.getElementById('botao').innerHTML = '<div class="protetor-botao"><a 
ef="javascript:download();">Fazer Download</a></div>';
}    }
//]]>
</script>

and you do not perform these functions. The code is very explanatory.

I would also like to do this redirection in PHP, as the example below: 

<?php
$url = $_GET['url'];
if (filter_var($url, FILTER_VALIDATE_URL) !== false) {
    header('Location: '.$url);
} else {
    die('Não é uma url');
}

This is the most suitable because you can record access metrics, such as date and time of access or even IP.

You can do this:

1) If you want to obfuscate your link, use the base64_encode 

base64_encode('http://google.com');

2) If you need to pass the parameter to the script, for example 

http://meusite.com/redirecionar.php?l=aHR0cDovL2dvb2dsZS5jb20=

Get the link inside the script. you can use something like: 

$link = base64_decode($_GET['l']);

3) To redirect, do not use the header() function if you are going to display some output before, this will generate an error, you need Javascript 

window.location = '<?php echo $link; ?>';

A simple way to implement what you're looking for with JavaScript might be: 

<html>
  <script>
    function redirect() {
      var match = /\?url=(.+)/.exec(window.location);
      if (match)
        window.location = match[1];
    }
  </script>
  <body onload="redirect();"></body>
</html>

Open this page as www.exemplo.com/redirect.htm?url=http://www.google.com/ .

You can take advantage of the same idea to make the waiting code or similar things.
