In a nutshell, HTTP will change to HTTP/2 in about a year or two from now and its main focus will be to decrease page loading times. You might have noticed that loading times have increased over the past few years, but that is mainly due to the improvements in broadband connections. To speed loading times up even more, the underlying HTTP needs to be updated.
You might be surprised to learn, that with all of the advances in digital technology and the way the internet has evolved over the years, HTTP has remained unchanged. It is way past time for an update, especially if we want to continue making use of the eCommerce web solution available for our websites.
