The Hypertext Transfer Protocol, or HTTP, defines how data travels on the web, including the billions of web page requests happening each day.

HTTP/2 is the most significant upgrade to the protocol in 20 years. The new standard is more efficient, which means faster, safer web traffic. HTTP/2 in Action introduces HTTP/2 and teaches you everything you need to use it effectively!

The Hypertext Transfer Protocol—HTTP—defines how data travels on the web and allows websites and browsers to send instructions, and hints to each other. It's the foundation of how we interact with the world wide web, and after 20 years it's finally gotten a major upgrade.

HTTP/2 introduces request multiplexing and request prioritization, which allows the web to to handle the ever increasing traffic that makes up modern websites better and header compression, which reduces the overall volume of data in transit with each web request. The new protocol also offers better support for modern techniques not anticipated by the original standard, such as server push.

HTTP/2 in Action is a complete guide to HTTP/2, one of the core protocols of the web. Because HTTP/2 has been designed to be easy to transition to, including keeping it backwards compatible, so adoption is already rapid and only expected to increase over the next few years.

Concentrating on practical matters, this interesting book presents key HTTP/2 concepts such as frames, streams, and multiplexing and explores how they affect the performance and behavior of your web sites. You'll learn what you need to change and how to deal with a web-in-transition as more sites begin to use the new protocol.

With the ready-to-implement tips and best practices on everything from server push to debugging, this book is sure to get you—and your websites—up to speed with HTTP/2!

Written for developers or website administrators with a basic understanding of web development. Some chapters use JavaScript-based examples but the techniques should apply to any HTTP/2 implementation.
