Symfony 3.4 Cache Control

To control caching in Symfony 3.4, you can use the built-in HTTP cache control headers provided by Symfony's Response object. Here's how you can set cache control headers in Symfony 3.4:

use Symfony\Component\HttpFoundation\Response;

$response = new Response();
$response->headers->set('Cache-Control', 'public, max-age=3600');

In the example above, the Cache-Control header is set to allow public caching for a maximum of 3600 seconds (1 hour). You can modify the cache control directives according to your specific requirements.

Please note that Symfony 3.4 is quite outdated, and it is recommended to upgrade to a newer version for better performance, security, and features.
