About the Book

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.

About the Author

Marcus Bointon

@SynchroM

Hello!

I'm Marcus Bointon, a skier, software developer, entrepreneur, and privacy advocate. My journey with computers began in the 1980s, through two computing degrees, numerous support roles (including for HP and Apple), and I've been a professional developer since the 1990s.

Currently, I'm engaged in writing and pentesting for Radically Open Security, developing clubzero.co and smartmessages.net, and supporting  1CRM and RUSI in the UK.

I'm a contributor to numerous open-source projects, including WordPress and Laravel, but I'm mostly known as the maintainer of PHPMailer, the second-most forked PHP project on GitHub, and likely the world's most popular email sending code; as a bonus, I wrote the HTML5 email address spec.

I have strong skills in PHP coding, Linux system administration, technical writing, and MySQL admin. I'm a passionate advocate for digital rights and privacy, including GDPR. Since 2006, I've been speaking at technical conferences around the world. Electronic music is something of a passion, and I write songs about open source! Though originally British, I'm now French, and I live in the French alps with my wife, kids, cat, guitars, bikes, and perhaps too many skis.
