How to cache static content (css, images, js files) in CakePHP2?

Question

I need to set some HTTP headers "Expires", "Cache-Control", "Last-Modified" for resources in the form of CSS files, image files, js files, etc. (Webroot content).

I read that there are some functions through

   Configure::write('Asset.timestamp', true); // In core.php

and the assetTimestamp method of the Helper class.

Now the question is: how is it used?

I read the HtmlHelper code and in the css method, line 361 there:

$url = $this->assetTimestamp($this->webroot($path));

$filepath = CSS . $regs[1]; //There are some variables that are can be used in this script, take a look to de docs.

header("Content-Type: text/css");
header("Expires: " . gmdate("D, d M Y H:i:s", time() + DAY) . " GMT"); //WEEK or MONTH are valid as well
header("Cache-Control: max-age=86400, must-revalidate"); // HTTP/1.1
header("Pragma: cache");        // HTTP/1.0
print $output;
