varnish Varnish: Speeding up your website with HTTP reverse proxy caching 7 hours Varnish is a reverse proxy for content-heavy dynamic web sites. Unlike Squid, which was originally a client-side cache, or Apache and nginx, which are web servers, Varnish was designed as an HTTP accelerator.

Varnish is used by Wikipedia, The New York Times, Facebook and Twitter, among other high-profile websites. In this course, participants will learn about Varnish's features and caching approach while practicing in the setup and configuration of a Varnish proxy on Linux. The course starts with a refresher on key networking principles, then digs into setup and configuration topics and moves steadily towards complex implementations. By the end of the training participants will understand when and where it makes sense to deploy Varnish and will have the necessary practice to deploy their own Varnish proxy solutions.
