What are HTTP Return Codes

HTTP status codes are standardized codes in the Hypertext Transfer Protocol (HTTP) used by web servers to indicate the status of a requested URL's response. These codes are part of the server's response to the client, which often is a web browser or other HTTP client. Each status code provides insight into how the server handled the request.

HTTP status codes are divided into five categories, each identified by the first digit of the code:

• 1xx (Informational): These codes indicate that the request was received and the process is continuing. Example: 100 Continue — The server has received the request headers, and the client should proceed to send the request body.
• 2xx (Successful): These codes indicate that the request was successfully received, understood, and accepted. Example: 200 OK — The standard response for successful HTTP requests. The actual response will depend on the request method used.
• 3xx (Redirection): These codes indicate that further action needs to be taken by the client to complete the request. Example: 301 Moved Permanently — This and all future requests should be directed to the given URI.
• 4xx (Client Error): These codes indicate that there was likely an error in the request which prevented the server from processing it. Example: 404 Not Found — The requested resource was not found on the server.
• 5xx (Server Error): These codes indicate that the server failed to fulfill a valid request. Example: 500 Internal Server Error — A generic error message when the server encounters an unexpected condition.

HTTP status codes are a fundamental part of web communications, providing quick insights into the transactional status of HTTP requests and responses, guiding subsequent actions by clients, and aiding in the proper functioning of web services and APIs.
