Reverse caching proxies like Varnish are a first-class citizen in Plone. In this session, we’re going to take a look at how to integrate Varnish into your Plone project, to increase performance and scalability.

We'll cover the basics of Varnish, learn how to set it up and configure. We'll also learn how to configure Plone for caching proxies, how to expose the right caching headers and how to correctly invalidate the cache when content updates happen.

VCL, the built-in programming language of Varnish, will be used to tailor the caching behavior to Plone's needs, and we'll also look at some deployment scenarios using traditional servers, in the Cloud, or on Kubernetes using the official Varnish Helm chart.

And at the end of the session, we’ll also cover some advanced scenarios that require the use of Varnish Enterprise.
