HTTP.fyi - What is HTTP?

HTTP (Hypertext Transfer Protocol) is the foundation of data communication on the web. It defines how messages are formatted and transmitted, and how web servers and browsers should respond to various commands.

When you type a URL into your browser, HTTP is the protocol that your browser uses to request information from the server hosting the website. The server then responds by sending the requested content back to your browser, which displays it as a web page.

HTTP is crucial to the functioning of the web, enabling the seamless exchange of information that powers everything from simple websites to complex web applications.
