Thelia implements the symfony 2 reverse proxy. To activate it, just edit the web/index.phpand uncomment all references to HttpCache :

use Thelia\Core\HttpKernel\HttpCache\HttpCache;
use Thelia\Core\Thelia;
use Thelia\Core\HttpFoundation\Request;

$env = 'prod';
require __DIR__ . '/../core/bootstrap.php';

$request = Request::createFromGlobals();

$thelia = new Thelia("prod", false);
$thelia = new HttpCache($thelia);
$response = $thelia->handle($request)->prepare($request)->send();

$thelia->terminate($request, $response);

A module can be use to easily add an expiration time on each route or disable the caching process : HttpCaching module

ESI tag

Symfony 2 reverse proxy supports esi tag, just as varnish supports it. Using this feature it’s easy to replace the symfony 2 reverse proxy by varnish.

ESI tags are html tags interpreted by some reverse proxy, they are usefull for creating some fragments in your templates that can have a different cache expiration or simply no cache like the mini cart.

By using the render_esi function in your template, Thelia render the esi tag when you are in production mode or the html fragment if you are in development mode.


{render_esi path="http://domain.tld/esi_resource"}

The path must be an absolute url, you can use some helpers like url function
