Http error 418 unused
Usefulness is a subjective measure, of course, but usefulness in jokes/play is still usefulness. Not all codes are from HTTP RFCs and I also think the "bug" here is that IANA has ignored rfc2324 for too long and should recognize the RFC as a valid HTTP extension with useful HTTP status codes. Note for instance all the ones from rfc4918 which is the WebDAV extension to HTTP, such as 424 and 507. The HTCPCP argument isn't all that valid as there are several recognized (IANA) HTTP codes from HTTP extensions like HTCPCP. There's not really even a strong technical reason why they are three digit codes to begin with in plaintext HTTP, it's just an arbitrary choice. In HTTP/1.x the status codes are plaintext and it's not like it would be that much of a change to most HTTP parsers.
HTTP ERROR 418 UNUSED CODE
rfc2324 which defines the code is indeed not HTTP, it is HTCPCP (Hypertext Coffee Pot Control Protocol) and one could strongly argue that it doesn't belong in an HTTP library.Īt the point in the distant future where you are worried about needing more HTTP error codes and considering reusing 418 it may just be easier to just add more digits to the protocol. With that said, another part of the argument is valid. The node community can't decide unilaterally to change code points. Second, "we may need this code point" is disingenuous unless the user is part of the W3C there is no "we" here. The backwards compatibility issue won't be any more/less of an issue then than now. įirst, you can remove it when there this problem actually happens. > While we have a number of spare 4xx HTTP status codes that are unregistered now, the semantics of HTTP are something that (hopefully) are going to last for a long time, so one day we may need this code point. And some of the reasons are kind of contrived. The API is also available at http. Qualsiasi tentativo di preparare il caffè con una teiera si tradurrà in un fallimento. Note that these responses actually have a body that the browser displays it's your proxy that hides this explanation.I find the initiatives like this to be kind of a waste of time. Errore HTTP 418 - T-Shirt Teiera ERRORE STATUS: Sono una teiera. In addition, it's a little easter egg you just found :) Long story short: There's not really a good status code for this case, so I figured we might as well return a 418. It is, sadly, only an informational RFC and not a standard (proposed or otherwise). And HTTP '418 Im a teapot' is defined by an RFC along with modifiers for milk-type, syrup-type, and alcohol-type. Me: > Authorization will not help and the request SHOULD NOT be repeated.Ĥ12 Precondition Failed was also suggested, but that's not applicable either, since a "precondition" is a pretty specific thing in that context. HTTP Status Codes are defined by IETF RFCs, not by IANA. Marc: 403 seems more apt, but I can get with 418 Me: There's really no good HTTP status code for an XSRF violation, but it feels like it should be a class 4 code. While implementing this change, I was considering what HTTP status code to return in such a case. It is, for instance, sending a standard HttpWebRequest pointed at with the client's cookies/useragent forwarded, method set to POST and post values of the following:Ī while ago we finally switched the response to CSRF violations from a non-descript error page, as we had been doing for years, to something sensible that somewhat explains what's going on.
I will not dispute that this may be a result of my reverse proxy not doing something exactly the same as a browser, and because that is an OAuth authentication page and there may be some security or something, but perhaps it should be returning a more appropriate HTTP response?Īs requested, more information about the post request my client is sending. I would at first have thought "Bug", but it is obviously not, because, well - how would you end up with an HTTP server returning 418 without doing it on purpose.
HTTP ERROR 418 UNUSED HOW TO
A year or so ago I got intrigued about how to properly implement custom HTTP errors on NGINX after watching this rather funny DEFCON talk. Implementing HTTP 418 Errors on NGINX NGINX Tricks Part 2 By GrumpyTechie on Septem ( 4). The pages I have found to return 418 with my reverse proxy are and 2.1.2 GET method In HTTP, the GET method is used to mean 'retrieve whatever information (in the form of an entity) identified by the Request- URI.' If the Request-URI refers to a data-producing process, it is the produced data which shall be returned as the entity in the response and not the source text of the process, unless that text happens to be the output of the process. Home Tech Implementing HTTP 418 Errors on NGINX NGINX Tricks Part 2. Why would Stack Exchange ever be set up to return this status code? I was just playing around and everything was working perfectly, until I hit one page that suddenly returned HTTP error code 418 (I'm a teapot) which was an april fools joke from Hyper Text Coffee Pot Control Protocol.
I recently wrote a reverse proxy which I have found to work wonderfully so far, and being an avid Stack Overflow user, I thought I would try it out there.
