via ssh), but it may be because the user is already authenticated and does not have authority. the response from a RFC2617 Authentication attempt). Can repeat with other credentials. For truly "malformed data", they would log the error so the the bug in the method that generates the request could be fixed. –Josh Noe Feb 19 '13 at 18:59 6

Authorization will not help ... Thus, I consider that HTTP spec does not allow 400 for failed validation on application level. –qarma Sep 23 '14 at 12:22 | show 6 more comments up vote 211 down By returning a 403 you are letting the client know it exists, no need to give that information away to hackers. If the server does not wish to make this information available to the client, the status code 404 (Not Found) can be used instead.

It implies "if you want you might try to authenticate yourself". What I've read on each so far isn't very clear on the difference between the two. Is the domain of a function necessarily the same as that of its derivative? This says: "I heard you, it's here, but try this instead (you are not allowed to see it)" share|improve this answer answered Dec 12 '14 at 19:01 Shawn 1 add a

It actually comes from WebDav but it is perfectly valid to reuse any status code that has been registered with IANA. –Darrel Miller Jul 20 '10 at 19:38 8 So And that’s just it: it’s for authentication, not authorization. Update From your use case, it appears that the user is not authenticated. Repeating will not work.

Only then DS.Errors will be populated with returned errors. I typically use this status code for resources that are locked down by IP address ranges or files in my webroot that I don't want direct access to (i.e. If the server does not wish to make this information available to the client, the status code 404 (Not Found) can be used instead In other words, if the client CAN Generating a sequence of type T at compile time Where I can learn Esperanto by Spanish?

Section 6.5.3 in this draft (authored by Fielding and Reschke) gives status code 403 a slightly different meaning to the one documented in RFC 2616. If the request already included Authorization credentials, then the 401 response indicates that authorization has been refused for those credentials. ... 403 Forbidden (10.4.4) Meaning: Unrelated to authentication ... OWASP has some more information about how an attacker could use this type of information as part of an attack. Not the answer you're looking for?

Whatever convention you use, the important thing is to provide uniformity across your site / API. The only other alternative is 422 Unprocessable Entity. Also, you aren't taking advantage of a JSON-ready parser; in contrast, a 422 with a JSON response is very explicit, and a great deal of error information can be conveyed. more stack exchange communities company blog Stack Exchange Inbox Reputation and Badges sign up log in tour help Tour Start here for a quick overview of the site Help Center Detailed

Speaking of JSON response, I tend to standardize on the Rails error response for this case, which is: { "errors" : { "arg1" : ["error msg 1", "error msg 2", ...] My reasoning is that it's not that the server refuses to fulfill request, it's that the server can't fulfill the request. –tybro0103 Aug 23 '13 at 19:16 | show 12 more What use cases are appropriate for each response? Authentication and Authorization are NOT interchangeable –BozoJoe Oct 17 '13 at 20:24 1 @BozoJoe we all agree on the difference between unauthorized and unauthenticated.

with a custom header - X-Status-Reason: Validation failed). This is essentially a 'HTTP request environment' debate, not an 'application' debate. Possibly there are credentials with permissions to access the resource, possibly there are not, but let's give it a try and see what happens. 403 indicates that the resource can not If you want generic, 400 is OK. 422 is used by an increasing number of APIs, and is even used by Rails out of the box.

Based on RFC 7231 and RFC 7235, I don't see an obvious distinction between 401 and 403 –Brian Feb 27 '15 at 15:20 403 means "I know you but The client SHOULD NOT repeat the request with the same credentials. If the request method was not HEAD and the server wishes to make public why the request has not been fulfilled, it SHOULD describe the reason for the refusal in the Receiving a 403 response is the server telling you, “I’m sorry.

How do you say "enchufado" in English? If the user is not logged in they are un-authenticated, the HTTP equivalent of which is 401 which is misleadingly called Unauthorized. I would return 401. However, I would expect that 401 to be named "Unauthenticated" and 403 to be named "Unauthorized".

The client MAY repeat the request with new or different credentials. Authorization will not help and the request SHOULD NOT be repeated. If so, why is it allowed? It neither suggests nor implies that some sort of login page or other non-RFC7235 authentication protocol may or may not help - that is outside the RFC7235 standards and definition.

Authentication by schemes outside the scope of RFC7235 are not supported in HTTP status codes and are not considered when deciding whether to use 401 or 403.

However, a request might be forbidden for reasons unrelated to the credentials. share|improve this answer edited Aug 29 '14 at 14:46 answered Feb 27 '13 at 9:44 Erwan Legrand 1,9911514 1 This is interesting.
