HTTP STATUS CODE
When browsers send requests to servers they respond back with HTTP status codes three digits long Here’s an overview of those codes in sixty seconds Codes starting with one give some information while the connection is still in progress Codes starting with two mean a successful connection was made 200 says everything's okay but 201 through 206 means is more happening, like new resources were created or there wasn't any content to send back. Codes starting with three indicate redirection, like 301 for permanent redirects or 302 and 307 for temporary redirects Codes starting with four show there was a client-side error like 404 if a requested resource doesn't exist or 403 if the user isn't allowed access Codes starting with five indicate a server-side error like failed database connection or the server being down That’s HTTP status codes in 60 seconds
