HTTP

May 1, 2024 Updated May 9, 2025 36 minute read

Hypertext Transfer Protocol, or HTTP, is the fundamental protocol used for transmitting data over the World Wide Web. It's the language that web browsers and web servers use to "talk" to each other, enabling you to view websites, watch videos, and interact with online applications. At its core, HTTP is a client-server protocol, meaning that requests for information are initiated by the recipient, which is usually your web browser. When you type a website address or click a link, your browser sends an HTTP request to a web server, which then processes the request and sends back an HTTP response containing the website's content.
