Symfony under the hood

Symfony has a wide userbase today. Most developers working with Symfony on a daily basis have configured their own services, are fluent in configuring routing and validators.

But what is actually going on under the hood? What happens when the configuration is parsed? What is a cache warmup? What happens to a request before hitting your controller? How does the HttpKernel work? In this workshop, we'll use some features of Symfony that may be less well known to users of the Framework, but that can be a great benefit - we'll build compiler passes, cache warmers, add custom authorization features, and more.
