Can HTTP 204 have body?
A 204 response is terminated by the first empty line after the header fields because it cannot contain a message body. A 204 response is cacheable by default; i.e., unless otherwise indicated by the method definition or explicit cache controls1.
Which HTTP status code category is used in the response to indicate that a REST API request contains an error on the client side?
400 is the generic client-side error status, used when no other 4xx error code is appropriate. Errors can be like malformed request syntax, invalid request message parameters, or deceptive request routing etc. The client SHOULD NOT repeat the request without modifications.
What does it mean when a HTTP response code is sent?
This interim response indicates that everything so far is OK and that the client should continue the request, or ignore the response if the request is already finished. This code is sent in response to an Upgrade request header from the client, and indicates the protocol the server is switching to.
What does it mean when your HTTP status code is not acceptable?
406 (Not Acceptable) The 406 error response indicates that the API is not able to generate any of the client’s preferred media types, as indicated by the Accept request header. For example, a client request for data formatted as application/xml will receive a 406 response if the API is only willing to format data as application/json.
When to use user 9 in response to a GET request?
You haven’t begun, nor will you begin, construction of user 9 in response to a GET request. That breaks all sorts of rules. 400 is used in response to a poorly formatted HTTP request (for instance malformed http headers, incorrectly ordered segments, etc).
What does unauthenticated mean in the HTTP standard?
Although the HTTP standard specifies “unauthorized”, semantically this response means “unauthenticated”. That is, the client must authenticate itself to get the requested response. This is an experimental API that should not be used in production code. This response code is reserved for future use.
