HTTP status codes and methods are critical elements in the Internet ecosystem and form the backbone of communication between web servers and clients. Anyone who has ever visited a website has interacted with these mechanisms, often unnoticed. For example, when a page is not found, one encounters the familiar "404 Not Found" status code. At such a moment, it becomes clear how closely linked our online experiences are to these codes. In the complex choreography of web traffic, HTTP methods serve as directional guides indicating what action should be performed, while HTTP status codes inform us of the success or failure of those actions. This dual system provides clarity and efficiency to the web's traffic, allowing websites and web applications to interact smoothly with a variety of endpoints and users. It is a language that remains mostly invisible, yet plays a central role in the digital world that surrounds us.
