From HTTP/1 to HTTP/2

Providing a consistently fast and reliable shared hosting service for our Vodien customers is no easy task but we are always on our toes to ensure that we equip them with nothing but high-performing tools and technology for superior website performance.

HTTP/2 is the latest HTTP successor designed by Engineering Task Force (IETF) to fix limitations found on HTTP/1.1. It provides a much-needed refresh in terms of security, speed and reliability to keep up with the rapid growth of websites.

If you’re already familiar with HTTP/1.1, it’s an underlying protocol that lays the foundation of how the World Wide Web functions.It defines how digital communication is formatted and delivered between web servers and browsers.

Since it requires loading a huge number of files to run websites today, the legacy HTTP/1.1 implementations may bring about certain limitations. One of the feared limitations is the increase in latency (amount of time to deliver the packet from one network to another) causing web page slowdown.

Introducing HTTP/2, a solution to the limitations of HTTP/1.1 and more.

 

Benefits of  HTTP/2

Websites that switch to HTTP/2 will experience the huge difference instantly.  Here’s a summary of the benefits:

  • Faster Web Page Loading Speeds – HTTP/2 will help make the browsing experience much faster than its old version since it eliminates known flaws and limitations.
  • Mobile-friendly – With the header compression enhanced, it helps mobile sites with high volume of requests to prevent from downloading wasted bandwidth from the header.
  • Better Security – Since HTTP/2 already has encryption enabled by default, it further reinforces security among websites using this protocol.
  • Compatible with HTTP/1.1 – For servers and browsers that still runs on HTTP/1.1, they may still communicate seamlessly with HTTP/2-powered browsers and servers. Both protocols have the ability to choose which version to use when communicating with each other.

 

What is HTTP/2?

As mentioned above, HTTP/2 is the latest HTTP successor designed by Engineering Task Force (IETF) to fix limitations found on HTTP/1.1. HTTP/2 aims to achieve these objectives by decreasing latency in browser requests through capabilities such as compression, multiplexing, server push and request prioritisation. Changes in HTTP/2 are meant to be compatible with HTTP/1.1.  

 

Improved Features of HTTP/2

Improved Features of HTTP/2

Multiplexing

One of the striking limitations with HTTP/1.1 is that it can only transfer one request per TCP connection at a time. This forces browsers to utilise multiple TCP connections to simultaneously handle multiple requests.

With HTTP/2, multiple HTTP requests are now possible on just one TCP connection. This means that transferring resources to a website will be faster and more efficient.

 

Server Push

HTTP/2 uses a procedure called server push where servers understand which files the browser need before the browser requests for them.

The server will technically “push” these files to browsers before the latter can even request for them. This makes the entire process of retrieving all resources needed to run a website faster.

 

Binary Protocols

HTTP/1.1 processes text-based commands to complete requests which may transmit excess data. HTTP/2 cuts down the amount of data transmitted by implementing it through the binary protocol which simplifies how a client’s computer interprets the transmitted information. This saves time translating information from a text to binary. This can significantly improve load time and overall performance.

 

Header Compression

For media-rich websites, clients have to push multiple header frames; this leads to latency and uses extraneous consumption of network resources. HTTP/2 addresses this issue by compressing a large size of redundant header frames.

It uses HPACK compression which compresses individual value for each header before transmitting it to the server. It then searches the encoded information from a list of previously transmitted header values to reassemble the full header information.

 

Stream Prioritisation

One of the weaknesses of HTTP/1.1 is the minification of CSS files and JavaScript. This is to reduce bandwidth and boost performance based on smaller file sizes.  

The implementation of HTTP/2 prioritisation allows clients to provide preference over particular data streams. This means that only the codes needed by a certain web page will be served to visitors. Since requests are simultaneous on HTTP/2, loading several small stylesheet files will not be a problem.

 

Can I Implement HTTP/2 on my Website?

The answer will depend if your web server supports HTTP/2. The majority of the web servers like Apache, IIS and NGINX already have support for HTTP/2.

However, even if you are using any of these servers, this does not mean that your site supports HTTP/2. Ultimately, it depends if your web hosting service provider has implemented the servers’ current software version to enable HTTP/2. We’re happy to announce that Vodien is one of the few web hosts that is HTTP/2-capable.

 

Which Browsers Support HTTP/2?

Browsers that support HTTP/2

If your visitor uses a non-HTTP/2 browser, backwards compatibility will come in place and your site will revert to using the HTTP/1.x connection. What’s great is that most of the browsers now support HTTP/2. The list of browsers includes Chrome, Opera, Safari, Firefox and others. You can check out Akamai’s tool to see if your browser supports HTTP/2.

HTTP/2-supported browsers only allow HTTP2 connection over Transport Layer Security (TLS). This means that your site needs to be on an encrypted connection. You will have to purchase and install an SSL certificate for your website to enjoy the benefits of HTTP/2.
