Every time you click a link, refresh a page, or submit a form online, a silent conversation takes place behind the scenes between your browser and the server hosting the website. This intricate dance relies on a language called Hypertext Transfer Protocol (HTTP), and just like any language, it has its own set of codes to convey messages. These codes are known as HTTP status codes, and understanding them can demystify the web and empower you as a user or developer.

What are HTTP Status Codes?

Imagine you send a letter requesting information. The response you receive might be positive ("Information found!"), negative ("No such information exists"), or somewhere in between ("Wait a minute, let me check that again"). Similarly, HTTP status codes are three-digit numbers that servers use to respond to requests initiated by your browser. Each code conveys a specific message about the outcome of your request, helping both humans and machines interpret the situation.
