HTTP status codes are essential components of the internet's communication protocol, serving as crucial messages between a web server and a browser. These three-digit numerical codes signify the outcome of an HTTP request, providing valuable information about the success, failure, or redirection of a particular web page's loading process. Each status code carries its own distinct meaning, offering insights into issues encountered during the interaction between a client (like a web browser) and a server. Understanding these codes is fundamental for web developers, system administrators, and anyone involved in managing or troubleshooting web-related issues.
