What happend to the `If-Modified-Since` header?

If-Modified-Since, PHP CLI Server and Firefox

Explanation

When sending the cache control header Cache-Control: no-cache, must-revalidate along with a Last-Modified timestamp, the browser is required to send along an If-Modified-Since header for the next request to the same URL.

The server then is entitled to return HTTP/1.1 304 Not modified in case the content didn't change and the stored copy may still be used.

Sample Code

<?php declare(strict_types = 1);
namespace test;
use DOMDocument;
use Templado\Engine\SimpleSnippet;
use Templado\Engine\SnippetListCollection;
use Templado\Engine\Templado;
require __DIR__ . '/vendor/autoload.php';
