What are Response Codes?
Response codes - also known as HTTP status codes - are three-digit numbers that servers use to communicate with a web browser about the outcome of its request to access a website.
When a browser tries to visit a website, it sends a request to that site's server. The server then replies with an HTTP status code, indicating the result of the request.
These codes act as a form of dialogue between the browser and the server. They inform the browser about the status of its request, whether it's successful or has some issues. This communication is crucial for the overall functioning of the web.
