This book offers an easy-to-understand overview of HTTP/3, the latest version of the hypertext transfer protocol, and QUIC, the new transport protocol designed to enhance the speed, security, and reliability of internet connections. As replacements for HTTP/2 and TCP, these protocols aim to solve persistent issues and bring useful improvements to web performance, particularly for those that need it most.

Whether you're a web developer, a networking beginner, or simply curious about how the web works, this guide provides a clear and concise explanation of these modern technologies.

The idea is not to overwhelm you with extreme detail, or provide an exhaustive reference – there is too much to cover in the stack of RFCs that make up the entirety of HTTP/3 and QUIC, and you don't need to know most of those details if your primary objective is just to get your site served securely and reliably over HTTP/3.

We'll take a look at how we got to this point, why these new protocols were needed, explore the basics of HTTP/3 and QUIC, and how to deploy and test your configuration. By the end, you'll have a solid foundation to understand these new technologies, their impact on the web, and know how to use them to deliver your own web services.
