HTTP/3 Prioritization?
Description:
Dive into the intricacies of HTTP/2 prioritization in this 51-minute conference talk from performance.now() 2019. Explore how HTTP/2 prioritization interacts with browsers and content, learn optimization techniques, and discover potential pitfalls in production environments. Gain insights into validating deployments for optimal performance. Examine recent developments in HTTP/3 and its impact on prioritization. Access accompanying slides for visual reference and follow the speaker's social media for further insights. Delve into topics such as basic parser rules, late-discovered resources, optimal script and resource loading, cross-connection prioritization, and connection coalescing. Investigate performance monitoring techniques, TCP buffering issues, and server HTTP/2 implementations. Conclude with an introduction to HTTP/3 and QUIC, preparing for future web performance challenges.
