ThijsFeryn / symfony_esi.php
Last active November 9, 2015 13:33
A page built using Symfony Components containing 3 content blocks: the main content block with a TTL of 10 seconds and 2 content blocks loaded via ESI. The first one has a TTL of 20 seconds, the second one doesn't cache
<?php
require_once __DIR__.'/vendor/autoload.php';
use Symfony\Component\HttpKernel\HttpCache\Esi;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
$esi = new Esi;
$request = Request::createFromGlobals();
$response = new Response();
$content = '<h1>This pages refreshes every 10 seconds</h1>';

Simple ESI rendering example using Silex and Varnish v4. The render_esi function in Twig renders ESI tags when the right Surrogate-Capability header is thrown, otherwise it uses internal subrequests.
