HTTP/2 is slowly taking over. How does this affect you?

HTTP 2.0: What you need to know about HTTP 2

What is HTTP? HTTP means Hyper Text Markup Language. It works for receiving, requesting and sending pages and data on the world wide web. Now, What is HTTP2? HTTP 2.0 is the latest invention of HTTP 1.1. HTTP 1.1 was first used and standardized near about two decades ago in 1997.

What is HTTP2:

HTTP/2 is described as HTTP 2.0. It is also called SPDY and pronounced Speedy. The latest version of HTTP has been developed by Google which is standardized and published in 2015. The standardization version is supported by all types of the popular browser including Chrome, FireFox, Internet Explorer 11, Safari, Amazon Silk, and Edge browsers. According to a research by W3Techs expressed that 12.7% of the top 10 million websites are supported with the latest version of HTTP (HTTP/2) until January 2017.

What you should be aware of HTTP 1.1:

No to mention, HTTP 1.1 first came to us in 1997. But it has some issues which are backdated including…

  1. HTTP 1.1 was introduced when the web was under 100KB. (Surprisingly, back then, it rarely cross the size of 100KB)
  2. CSS (Cascading Style Sheet) was not discovered at all and JavaScript was planning to enter the web world.
  3. HTTP 1.1 was something on the World Wide Web which is used for simple validation and special effects.
  4. There has no use of High bandwidth, Ajax-powered, Single-Page Applications and client-side frameworks.
  5. No one can think to make any high standard web page rather than some information in small pages and more than a few requests.

Difference Between HTTP 1.1 and HTTP 2.0:

What advantages will you get in HTTP 2.0 and was absent in HTTP 1.1?

  1. HTTP 1.1 used textual data which was less efficient in the network, on the other hand, HTTP 2.0 is using binary data which is too fast and efficient.
  2. The main concept of HTTP 2.0 was to compress the header data but HTTP 1.1 was unable to do that. Generally, a connection sent a request describing the data in header including its origin, type, length, and how long it can be cached, etc. So, how fast a request is sent, it will reduce response time. So compressing data in the header was a big challenge in HTTP 1.1. But HTTP 2.0 has recovered it.
  3. In HTTP 1.1, it has the capacity to handle one request on a TCP connection only. As a result, when it opens more than one connection (Typically it opens four or Eight connection at a time) it would slow down the loading time of the server. On the other hand, HTTP 2.0 is capable of maintaining and sending multiple requests at the same time within one connection. Similarly, It has increased the loading and response time surprisingly.
  4. HTTP 2.0 can work to response smaller and sooner data very fastly as it uses pipelining. On the other hand, HTTP 1.0 was not able to work so fast. It only receives the request in an order.
  5. In HTTP 1.0, it loads the data in a sequence like when it receives a request, it will download the HTML file first and then it reads the <script> tag. On the other hand, HTTP 2.0 works as server push. As result, a server can easily puss so fast the JavaScript file without following any prioritization and knowing the requirement.

Why HTTP 2.0 is important:

Nowadays, every web page is using different components beside HTML including design elements (CSS), client-side scripting (JavaScript), Framework,  images, video and Flash animations. Important to realize, every information needs to create several connections. They have to collect information from different sources, destination, and contents. For this reason, they have to load huge file delivering the content in your browser. So, it can slow down your server. Significantly, it can reduce user-experience on your website.

To put it another way, webmasters are implementing techniques as like catching. By caching, a server can deliver your desired content from locally after their first load. On the other hand, many of us are using to reduce the file sizes of content including images and videos. With this attention, others are trying to optimize the code and all the reasons are offering to load the pages within milliseconds.

Specially, Google has replaced HTTP 1.1 to SPDY to do the same work and the result is impressive. Generally, in HTTP 2.0,  communication between the server and the browser is so speedy. As it implements encryption. HTTP 2.0 increases the loading time by 10 percent and many cases the improvement goes to 40 percent. Thus HTTP 2.0 start to take it establishment in the WWW world.

Why is HTTP 2.0 better:

By using HTTP 2.0, you are getting many advantages. In most cases, it is very amazing. I’ve listed some point of the good sides of HTTP 2.0 are…

  • HTTPwatch is showing that HTTP 2.0 has increased the data transfer speed by 20 percent. In some cases, the improvement is showing 30 to 40 percent which is a blessing for the internet world.
  • It transfers data in binary, which is the native language of a computer. So your computer does not need to waste time translating data into standard formats.
  • HTTP 2.0 is working by multiplexing. By this, a single request can receive and request multiple messages at the same time.
  • It has reduced the data by compression. Mainly it has compressed the data by squeezing information into smaller chunks.
  • It has enabled server push. So, it can guess what will be your next request and process the data by this.

Should you start using HTTP 2.0?

Yes! You should take the advantages of HTTP 2.0 quickly. The first thing to remember, only HTTP 2.0 can work both the web server and the browser at the same time. On the other hand, 12.7% of the top 10 million websites are using HTTP 2.0. Similarly, all the updated version of web browsers are supporting it including Chrome, FireFox, Internet Explorer 11, Safari, Amazon Silk, and Edge browsers.

How to check If your web host is enabled with HTTP 2.0:

If you have a website, you can check easily if your site or web host in enabled with HTTP 2.0. You have to enter your website’s URL into HTTP 2.0 Test Tool.

If you want to use HTTP 2.0 in your websites (managed or shared hosting), your host needs to enable it. For this reason, you have to contact with them. By all means, if you are using other hosting services, contact with your provider, they will give you the proper solution for using HTTP 2.0.

Do I need to update my website:

The clear answer is NO. Because, HTTP 2.0 is not fully compatible with HTTP 1.1. Before considering to move HTTP 2.0 you should know some issues from the experts or your hosting provider. Basically, HTTP 2.0 is more advanced than HTTP 1.1. But you have to learn it and implement it knowing all the component of it.


At last, I will tell, HTTP 2.0 is the latest invention in the web world. To get the full advantages of high speed and compressed web pages, you have to go with HTTP 2.0. As it is a new technology, everyone is trying to adapt with it. So carry on and start to learn more and start with new WWW.
