What is HTTP/2 All About?
The world wide web at large operates over the Hypertext Transfer Protocol (HTTP). HTTP was first conceived way back in 1989 and the last major revision was ratified in 1999. The Internet was quite different in those days. The majority of websites were text-based with very few images, scripts, and styles — and video was even rarer. Today, websites are much more interactive with images, animations, styles, custom fonts and much more, but this comes at a price, a single page can easily request over 100 different resources.
HTTP/2 aims to address many of the current failings of HTTP/1.1 by evolving the standard to meet the needs of modern applications.
