Скачать или смотреть Error 404 Page Not Found ! What is http status code ?

An HTTP status code is a three-digit number returned by a web server in response to a client’s request. These codes indicate whether the request was successful, encountered an error, or requires further action. They help browsers, search engines, and developers understand how a request was processed.

HTTP status codes are categorized into five classes:

1. 1xx (Informational): These indicate that the request has been received and is being processed. Example: 100 Continue.

2. 2xx (Success): These confirm that the request was successful. Example: 200 OK means the request was completed successfully.

3. 3xx (Redirection): These indicate that further action is needed, such as redirecting to another URL. Example: 301 Moved Permanently.

4. 4xx (Client Errors): These occur when the client sends a faulty request. Example: 404 Not Found means the requested page doesn’t exist.

5. 5xx (Server Errors): These happen when the server fails to fulfill a valid request. Example: 500 Internal Server Errors.

Understanding HTTP status codes is essential for debugging website issues, improving user experience, and ensuring smooth web communication. Web developers and SEO professionals use these codes to optimize website performance and handle errors effectively.
