What is HTTP/2

HTTP/2 is a major revision of the HTTP network protocol used by the world wide web. It is designed to make applications faster, simpler and more robust by improving the way that browsers and servers communicate with each other. This allows for faster transfer of information while reducing the amount of raw horsepower needed, a bit like the eco-friendly turbo petrol engines you find cars these days.


What makes HTTP/2 faster?

By creating a constant connection between the browser and server, instead of new a connection every time a new piece of information is needed, means that less data needs to be transferred. The data is being transferred is also in binary instead of the text that was used in HTTP/1. No more need for translation.

Other features are “Multiplexing”, the simultaneous sending and receiving of multiple messages. The Prioritisation of information, so it serves what the user needs first. It compresses the information into chunks and makes use of “server push”, where the server makes an educated guess where the user is going to go next and proactively loads that information.

How could HTTP/2 affect your website?

HTTP/2 is dubbed a “faster, more secure” platform which is great for all users. A faster load time generally means a that there will be a slick experience for users, and if you are aiming for the top spots on google, then this is great for your SEO. And, in the mobile-first world, we live in, load time is extremely important.


What do you need to do to reap the rewards of HTTP/2?

Firstly, you need to make sure your website is HTTPS, which is a simple process, just contact your Web Design Agency if they haven’t already been in touch. If your website is already secured, you may only have to update your server software to the latest version.

As with many of our clients that have made the upgrade to HTTPS, you may already be on HTTP/2 without knowing that the switch had happened as part of a server update. You can use SPDYCheck to find out.?

As it stands, there are no significant drawbacks to making the switch for website owners, but the rewards are long-lasting and will help to create a better, faster, more secure web experience for all users. What are you waiting for?
