Prerequisite Knowledge

A basic understanding of caching technologies including time-to-live and HTTP cache-control/expires headers is required.

Materials or downloads needed in advance

Bring your laptop.


The “caching ecosystem” has evolved over the years – what, where, and how long you cache your web assets are now important considerations for anyone doing business on the internet. Browser cache, html5 application cache, sophisticated reverse proxies like Varnish, and the evolution of CDNs have all elevated caching as the single most effective tool for creating high performing and scalable web applications.

Using live demos, we will dive into some advance caching concepts that will enable you to squeeze the most benefits from this caching ecosystem, including:

  • Prefresh
  • Prefetching for sites
  • Prefetching for single page apps
  • Burst caching: caching for an extremely short burst of time, even a few seconds
  • Dynamic page caching
  • Cache invalidation and revalidation

However, with caching power comes caching responsibility. If not implemented correctly, these advanced techniques can degrade or even break site functionality. We will conclude with some practical exercises to define the caching strategy for key use cases:

  • E-commerce website
  • B2B application
  • Mobile application
  • High traffic events.
