200 OK

The 200 (OK) status code indicates that the request has succeeded.
The payload sent in a 200 response depends on the request method.
For the methods defined by this specification, the intended meaning

GET a representation of the target resource;

HEAD the same representation as GET, but without the representation

POST a representation of the status of, or results obtained from,
the action;

PUT, DELETE a representation of the status of the action;

OPTIONS a representation of the communications options;

TRACE a representation of the request message as received by the end

Aside from responses to CONNECT, a 200 response always has a payload,
though an origin server MAY generate a payload body of zero length.
If no payload is desired, an origin server ought to send 204 (No

successful result is a tunnel, which begins immediately after the 200
response header section.

A 200 response is cacheable by default; i.e., unless otherwise
indicated by the method definition or explicit cache controls (see
