A Practical Guide for Beginners
What can your organization gain by adopting HTTP/2? How about faster, simpler, and more robust websites and applications? This practical guide demonstrates how the latest version of the Hypertext Transfer Protocol can dramatically improve website and application performance. You’ll take a deep dive into more » HTTP/2 details, and learn how this updated protocol is changing the web landscape.
HTTP/1.1 has been the primary means of communicating data across the Web for the past 20 years, but the level of interaction today has gone well beyond what people envisioned in 1997. With this book, authors Stephen Ludin and Javier Garza show you how HTTP/2 will help speed the execution of modern sites and applications.
With this book, you’ll explore:
* Performance challenges that led to the HTTP upgrade
* HTTP/2 in a nutshell, including benefits and transition methods
* How Google’s SPDY networking protocol paved the way for HTTP/2
* Existing best practices and hacks to improve web performance
* HTTP/2 support for browsers, servers, proxies, and content delivery networks
* How the performance of sites using HTTP/2 compares to their HTTP/1.1 experience—including the good, bad, and the ugly
* HTTP/2’s effect on specific issues such as latency, packet loss, and Time to First Byte (TTFB) « less
Building Faster Web Pages
The content of the web is maturing and increasing in complexity, but internet infrastructure quality varies widely across the globe. People are browsing the web through a greater variety of devices and networks than ever before. Your website's visitors may be browsing via resource constrained connections, more » or limited by restricted data plans. Due to these hard realities, it's more important than ever that your website loads quickly, lest you alienate your visitors before they ever get a chance to see what your site has to offer.
Web Performance in Action is your companion guide to making websites faster. Throughout the course of this book, you'll learn techniques that speed the delivery of your site's assets to the user, increase rendering speed, decrease the overall footprint of your site, as well as learn how to build a workflow that automates common optimization techniques. You'll also get a look at new technologies such as HTTP/2 that will take your website's speed from merely adequate to seriously fast. « less
The new HTTP/2 standard is finally here. Approved earlier this year, HTTP/2 adds a new binary framing layer that will help make applications faster, simpler, and more robust. This chapter from the new release of High Performance Browser Networking provides a brief look at this updated protocol and explains more » how it will reduce latency, minimize protocol overhead, and add support for request prioritization and server push.
In this excerpt, author Ilya Grigorik takes you through HTTP/2's design and technical goals, and explains how Google's SPDY played a critical role in the protocol's development. You'll also learn what's required for upgrading a multitude of servers and clients to HTTP/2.
This excerpt covers:
- HTTP/2's binary framing layer
- Streams, messages, and frames
- Request and response multiplexing
- Stream prioritization
- One connection per origin
- Flow control
- Server push
- Header compression « less
