HTTP response status code is a 3-digit code returned by the server indicating the status of the request.
The code is typically accompanied by a message that provides additional information about the response such as:
2XX - Successful - Website is up & reachable.
3XX - Redirect - The website is accessible, but the browser is redirected to another page.
4XX - Browser Error - The requested page is not available or doesn’t exist.
5XX - Server Error - There are internal errors on the server.
The status code helps developers and users to understand what’s happening with a certain request.
This also serves as a guide to take appropriate actions if needed.
