Beyond Page Cache

One of the biggest misconceptions in web performance is that adding a CDN automatically makes websites fast. In reality, many traditional CDNs primarily accelerate static assets, while HTML responses still need to travel back to the origin server, resulting in high Time to First Byte (TTFB) for international users.

This session explores how TYPO3 can benefit from a true edge caching architecture using Fastly and Varnish-based caching. Using a real-world demo project, we will compare traditional CDN setups with full HTML edge caching and demonstrate how moving TYPO3 page delivery closer to the user can dramatically reduce latency and origin load.

Attendees will learn how TYPO3 cache headers, cache tags, and invalidation strategies integrate with Fastly, how VCL rules can handle authenticated users and dynamic content, and how edge-based image optimization can automatically deliver responsive AVIF and WebP images in the optimal size and format.

The talk focuses on practical implementation details, including:

• Differences between traditional CDNs and edge platforms
• Reducing global TTFB with HTML edge caching
• TYPO3-specific VCL handling and cache invalidation
• Managing dynamic and personalized content
• Edge image optimization and responsive image delivery
• Measuring cache hit ratios and frontend performance improvements

Attendees will leave with a practical understanding of how to build a modern TYPO3 delivery architecture that goes beyond traditional page caching.
