Book Description

HTTP/3, the latest version of the Hypertext Transfer Protocol, is the foundational layer of the web as we see. It opens the door for a faster generation of web applications with minimum latency. This book gives you an overview of the advantages, deep insights, and practical instructions for building new or upgrading existing web projects to the latest HTTP standard.

The book starts with a brief on the evolution of HTTP right from HTTP/1 to help you appreciate the journey to HTTP/3 and how we got here. You'll get a technical overview of HTTP/1, HTTP/2, and SPDY that powered the traditional web and then be introduced to the latest QUIC protocol that is foundational to the HTTP/3 standard. You'll understand the technical intricacies of the new IETF standards and how it fuels the faster web. The book covers practical techniques to get started with building web apps and migrating your existing projects to HTTP/3. Once you've learned the concepts of streams, connections, packets, and frames, you'll progress to header compression for HTTP/3 and how it helps you overcome congestion issues. Finally, you'll get to grips with techniques to analyze traffic and implement privacy.

By the end of the book, you'll have a solid understanding of the enhancements in HTTP and how to build and migrate existing projects to HTTP/3.
