This is a little techie, but funny. The point is that when your browser asks for a web page, the computer that sends the web page back to you includes a three-digit status code. The first digit says whether the request is in progress, was successful, had a client or server error etc. From Wikipedia:
- 1xx informational response – the request was received, continuing process
- 2xx successful – the request was successfully received, understood, and accepted
- 3xx redirection – further action needs to be taken in order to complete the request
- 4xx client error – the request contains bad syntax or cannot be fulfilled
- 5xx server error – the server failed to fulfill an apparently valid request
Anyway, this site will supply a cat picture (yes!) for each return code: https://http.cat/. Click on the picture for an expanded picture. Example: 400 = Bad Request:
