The error 404 is a standard HTTP status code that indicates the server cannot find the requested resource or webpage. This error is typically displayed when a user attempts to access a webpage that no longer exists or has been moved to a different URL.
The error 404 message usually includes a brief explanation of the error, such as “The requested URL was not found on this server” or “The page you are looking for might have been removed or had its name changed”. It may also include suggestions for what the user can do next, such as checking the URL for errors, using the search function on the website, or contacting the website’s administrator for assistance.
If you encounter a 404 error while browsing a website, you can try refreshing the page or using a different browser to see if that resolves the issue. If the error persists, it may indicate a problem with the website itself, and you may need to contact the website’s support team for further assistance.
HTTP status code
HTTP status codes are three-digit numbers that are returned by a web server to indicate the status of a client’s request to the server. The HTTP status codes are grouped into five categories, each represented by a range of three-digit numbers:
1xx Informational – These codes indicate that the client’s request has been received and the server is continuing to process the request.
2xx Success – These codes indicate that the client’s request has been successfully received, understood, and accepted by the server.
3xx Redirection – These codes indicate that the client must take additional action to complete the request, such as following a redirect.
4xx Client Errors – These codes indicate that the client has made an error in its request, such as requesting a resource that does not exist or attempting to access a resource that the client is not authorized to access.
5xx Server Errors – These codes indicate that the server has encountered an error while attempting to process the client’s request.
Some common HTTP status codes include:
- 200 OK – The server has successfully processed the client’s request.
- 404 Not Found – The server cannot find the requested resource or webpage.
- 500 Internal Server Error – The server encountered an error while attempting to process the client’s request.
- 301 Moved Permanently – The requested resource has been permanently moved to a new URL.
HTTP status codes are important for web developers and website administrators to understand, as they can provide insight into the cause of errors and issues that users may experience while browsing a website.
