Understanding  HTTP/2

Are you curious about HTTP/2 and wondering how it can speed up your website? Keep reading to learn more about the binary protocol, server push, and everything else HTTP/2 has to offer.

What is HTTP/2?

HTTP/2 is a web protocol that was designed to enhance website performance. It aims to improve the loading time of web pages by allowing multiple requests to be sent over a single connection. This new protocol replaces the older HTTP 1.1 that was introduced over 20 years ago.

How does HTTP/2 protocol work?

HTTP/2 uses a binary protocol, which compresses the data sent between the server and client, reducing latency and speeding up communication. It also has a feature called server push, where the server can send response data without waiting for a request from the client.

Why is HTTP/2 important for website speed?

HTTP/2 improves website speed by reducing page load times. By allowing multiple requests to be sent over a single connection, the amount of overhead is reduced, which in turn reduces latency. Additionally, server push helps to deliver resources more quickly by preemptively pushing them to clients before they are requested.

What is server push in HTTP/2?

Server push is a feature in HTTP/2 protocol that allows servers to send additional resources to clients before they have explicitly requested them. This feature helps reduce page load times by preemptively pushing resources such as images and scripts to clients without waiting for requests.

What are the benefits of using binary protocols like HTTP/2?

Binary protocols like HTTP/2 compress data more effectively than text-based protocols like its predecessor, HTTP 1.1. This compression reduces latency and speeds up communication between server and client.

Can all servers support HTTP/2?

Not all servers support the new protocol yet, but most popular web servers such as Apache and Nginx have implemented support for HTTP/2.
