HTTP/2: Explained

After over 15 years from the initial launch of the Hypertext Transfer Protocol, IESG approved HTTP/2 as the successor to the original protocol. This will bring a vast improvement in a lot of ways in the internet department.

Basically, the Hypertext Transfer Protocol is an application protocol for distributed, collaborative, hypermedia information system. That means that HTTP is the foundation of the web. Without this protocol, the web wouldn`t have existed or at least not like it is now.

HTTP functions as a request-response protocol in the client-server computing model. This means that the client is sending a request message to the server, then the server processes that information and sends the results back to the user. What the 2.0 protocol brings new to the table is multi-threading. That means that a client can send multiple requests messages at once. This basically means that, in theory, we will get faster internet.

The 2.0 promises to reduce latency and improve load speeds in web browsers. This will be achieved by compressing some of the data and by loading some page elements in parallel over a single TCP connection.

I know, it all sounds so good, but don`t get to excited about it. It will take a while until it is going to be fully implemented, if we take HTML 5`s adoption time, you`ll see what I’m talking about. It took from 2008 to 2013 to make it even work fully inside every major web browser. If you were thinking that from now on, the speed will be doubled over the night, or something like this, let me tell you that you are completely wrong. It will take time, and the speed will ramp up slowly.

To wrap things up, don`t think that this will make your website faster or anything. This is not a big evolution. It is surely an enormous step in the right direction, but is not an evolution by any stretch of the imagination.
