HTTP Caching with Varnish

With the Varnish caching proxy you can make websites blazingly fast, while also handling a lot more load. The key is to understand how cache handling in HTTP works. We will also look at concepts like cache invalidation and cache tagging, as well as advanced concepts like Edge Side Includes (ESI). A lot of this talk is applicable regardless of the programming language of your backend. Examples will use the PHP library FOSHttpCache and sometimes the Symfony FOSHttpCacheBundle.
