Understanding HTTP Status Codes

HTTP status codes are three-digit numbers returned by web servers to indicate the outcome of a request. They provide information about whether a request was successful, encountered an error, or needs further action.

Why check HTTP status codes? Monitoring status codes helps identify website issues, track redirects, optimize SEO, and ensure proper website functionality.

2xx - Success
2xx

The request was successfully received, understood, and accepted.

200 OK 201 Created 204 No Content
3xx - Redirection
3xx

Further action needs to be taken to complete the request.

301 Moved 302 Found 304 Not Modified
4xx - Client Error

400 Bad Request 403 Forbidden 404 Not Found
5xx - Server Error
