2×× Success

200 OK

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:

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 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 controls1.
