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 of the payload can be summarized as:
GET a representation of the target resource
HEAD the same representation as GET, but without the representation data
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 server.
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 Content)](/204) instead. For
CONNECT, no payload is allowed because the 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
