I know that status code 418 was defined as a April Fools' joke, and "is not expected to be implemented by actual HTTP servers" as is stated on Wikipedia.
But I would be interested if any of you knew of a language/webserver/IDE that supports it.
I was trying on Apache (via php), and obviously it got me an internal error (500). I just like the humor behind it (am not trying to troll here) and would like to know if more than just Emacs implements this.
More precisely: It could be emulated in php for example by doing something like ...
header("HTTP/1.1 418 Whatever text I'd like");
... but do any of you know any actual server software, or language in particular, that implements it natively, where something like the following would not throw a 500, but actually work:
http_response_code(418);
res.send(418)
Sends following HTTP header:
HTTP/1.1 418 I'm a teapot
Date: Wed, 25 Feb 2015 07:08:27 GMT
Connection: keep-alive
Transfer-Encoding: chunked
The actual node.js code used to get this response was:
require('http').createServer(function(q,s) {
s.writeHead(418);
s.end();
}).listen(80);
http.Error(w, http.StatusText(418), 418)
Within native libraries, starting from Python 3.9 (Details @Ross)
