Non-standard Status Codes

[ibnesayeed]

Find up to two "in the wild" examples of different response codes not defined in an RFC (e.g., 299 or 999). Standard HTTP status codes and their corresponding RFCs are listed in the HTTP Status Code Registry.

@Neyo-odu, I am glad that you found a 418 in the wild. This actually means I'm a Teapot which was defined in an RFC as an April Fool's joke. On the one hand it is actually defined in an RFC, on the other hand it is not listed in the IANA registry, so I will accept it as a valid submission.

That's very cool, I had no idea! Would I be able to use this one also?

The task is to find different response codes, so it's a no.

@himarshaj, we will not entertain services that allow clients to decide what status code or headers to get back. Things like getstatuscode.com or httpbin.org are good for testing, but not a good example to be claimed as "in the wild". Also, setting up your own site to satisfy certain requirements would be against the essence of these "in the wild" assignments.

This is a cloud-flare specific status code. Due to which means its not defined in any RFC or IANA
