General explanation of the 200 status code
The HTTP status code 200 OK signals that the server has successfully processed the client's request and returned a correct response. This means that the web page or resource that the client requested was found and successfully transmitted. It is a standard status code used for successful requests.
Specification of the HTTP status code 200
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 OK 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) instead. For CONNECT, no payload is allowed because the successful result is a tunnel, which begins immediately after the 200 OK response header section. A 200 OK 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]).Source / Quote by: The 200 OK HTTP Status Code is specified by section 6.3.1 of RFC7231.
