The 501 (Not Implemented) status code indicates that the server does not support
|
|
|
|
|
the functionality required to fulfill the request. This is the appropriate
|
|
|
|
|
response when the server does not recognize the request method and is not
|
|
|
|
|
capable of supporting it for any resource.
|
|
|
|
|
|
|
|
|
|
A 501 response is cacheable by default; i.e., unless otherwise indicated by the
|
|
|
|
|
method definition or explicit cache controls
|
|
|
|
|
(see [Section 4.2.2 of RFC7234][1]).
