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<sup>[1](#ref-1)</sup>.
