Review request for mesos, Alexander Rukletsov, Greg Mann, Joerg Schad, Jan
Schlicht, and Till Toenshoff.
Bugs: MESOS-4305
https://issues.apache.org/jira/browse/MESOS-4305
Repository: mesos
Description (updated)
-------
It is a common pattern within Mesos to return an HTTP 401 (Unauthorized)
response whenever the request is invalid for whatever reason. However,
according to the [RFC-2617 Section
1.2](https://tools.ietf.org/html/rfc2617#section-1.2):
> The 401 (Unauthorized) response message is used by an origin server to
> challenge the authorization of a user agent. This response MUST include a
> WWW-Authenticate header field containing at least one challenge applicable to
> the requested resource.
Meaning that despite the confusing name, the status code _401 Unauthorized_
should be used only for authentication purposes. On the other hand, the
[RFC-2616 Section
10.4.4](http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.4.4)
states:
> _(403 Forbidden is returned when)_ The server understood the request, but is
> refusing to fulfill it. Authorization will not help and the request SHOULD
> NOT be repeated. 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 entity. If the server does not wish to make
> this information available to the client, the status code 404 (Not Found) can
> be used instead.
As such, _403 (Forbidden)_ seems to be a better return code when replying
inside endpoint handlers, while _401 (Unauthorized)_ should be left to the HTTP
Authenticators only.
