What is an HTTP Status Code?
HTTP status codes are three-digit numbers returned by a web server in response to a client's request. They indicate whether a specific HTTP request has been successfully completed, needs further action, or has encountered an error. Status codes are part of the HTTP protocol and are included in the server's response header.
