HTTP status codes are used when communicating between the client and the server. When the client sends an HTTP request to the server, the server returns a status code related to the request as a response.

HTTP status codes provide information about the results of request processing so that the client can make appropriate processing based on different status codes. These status codes can tell the client whether the request is successful, whether redirection is required, whether there are errors, etc.

Some common HTTP status codes and their uses include:

• 200 OK: Indicates that the request was successful and the server has successfully processed the request and returned the required content.
• 404 Not Found: Indicates that the requested resource was not found, usually used to indicate an invalid URL or file path.
• 302 Found: Indicates that the requested resource has been temporarily moved to another location and the client should be redirected to the new URL.
• 500 Internal Server Error: Indicates that an error occurred inside the server and the request cannot be completed.

HTTP status codes are very important in web development, they help developers and system administrators detect and debug problems, and provide feedback to the client about how the request was handled. At the same time, the client can take corresponding actions based on the status code, such as displaying an error page, retrying the request, or automatically jumping to a new URL.
