What is HTTP?

Overview

The HTTP (Hypertext Transfer Protocol) and HTTPS (HTTP Secure) are two of the most commonly used protocols in internet-based applications and services.

HTTP is the protocol used to transfer data between a client (such as a web browser) and a server (such as a website). When you visit a website, your web browser sends an HTTP request to the server, asking for the webpage or other resource you've requested. The server then sends an HTTP response back to the client, containing the requested data.

HTTPS is a more secure version of HTTP, which encrypts the data being transmitted between the client and server using SSL/TLS (Secure Sockets Layer/Transport Layer Security) encryption. This provides an additional layer of security, helping to protect sensitive information such as login credentials, payment information, and other personal data.

Protocols play a critical role in enabling communication and data exchange over the Internet. A protocol is a set of rules and standards that define how information is exchanged between devices and systems.

HTTP/3 - 2022

HTTP/3 is the next version of HTTP. HTTP/3 is a QUIC-based protocol. QUIC is a transport layer protocol that is built on top of UDP and is designed to be a replacement for TCP. It is a multiplexed, secure, stream-based protocol that is designed to reduce latency and improve performance.
