DrupalCon Dublin 2016: Practical Caching in Drupal 8

This talk focuses on practical caching strategies in Drupal 8, addressing common challenges and misconceptions surrounding cacheability in real-world scenarios. The speaker explores three layers of caching: the anonymous page cache, which utilizes the Internal Page Cache module for storing cached pages for anonymous users; reverse proxy caching, detailing how to configure it with tools like Varnish or CDNs; and the authenticated page cache, which emphasizes secure and dynamic caching for logged-in users. The session also covers essential components such as caching metadata, cache contexts, and typical pitfalls with render arrays and custom controllers, providing attendees with the skills needed to optimize caching strategies effectively. By the end of the session, participants will be equipped to troubleshoot caching issues and enhance site performance.
