12. @zenstruck What Symfony2 is not MVC Framework
13. @zenstruck HTTP Framework Request Response
14. @zenstruck HTTP Framework Request Response I don't like MVC because that's not how the web works. Symfony2 is an HTTP framework; it is a Request/Response framework. That's the big deal. The fundamental principles of Symfony2 are centered around the HTTP specification. - Fabien Potencier

27. @zenstruck “Killer” Feature Symfony2 Reverse Proxy
28. @zenstruck 3 Types of HTTP Cache • From the docs: • Browser caches: Every browser comes with its own local cache that is mainly useful for when you hit "back" or for images and other assets. The browser cache is a private cache as cached resources aren't shared with anyone else. • Proxy caches: A proxy is a shared cache as many people can be behind a single one. It's usually installed by large corporations and ISPs to reduce latency and network traffic. • Gateway caches: Like a proxy, it's also a shared cache but on the server side. Installed by network administrators, it makes websites more scalable, reliable and performant.
