Shufti - 200 Status Code (Success)

200 is the Standard response for successful HTTP requests. The actual response will depend on the
request method used. In a GET request, the response will contain an entity corresponding to the
requested resource. In a POST request the response will contain an entity describing or containing
the result of the action.

This status code implies that the request has succeeded. The information returned with the response
is dependent on the method used in the request, for example:

GET: an entity corresponding to the requested resource is sent in the response

POST: an entity describing or containing the result of the action

201 (Created)

The request has been fulfilled and resulted in a new resource being created. The newly created
resource can be referenced by the URI(s) returned in the entity of the response, with the most
specific URI for the resource given by a Location header field. The response SHOULD include an
entity containing a list of resource characteristics and location(s) from which the user or user agent
can choose the one that is most appropriate. The entity format is specified by the media type given in
the Content-Type header field. The origin server MUST create the resource before returning the 201
status code . If the action cannot be carried out immediately, the server SHOULD respond with 202
(Accepted) response instead.

202 (Accepted)

The request has been accepted for processing, but the processing has not been completed. The
request might or might not eventually be acted upon, as it might be disallowed when processing
actually takes place. There is no facility for re-sending a status code from an asynchronous operation
such as this.

The 202 response is intentionally non-committal. Its purpose is to allow a server to accept a request
for some other process (perhaps a batch-oriented process that is only run once per day) without
requiring that the user agent’s connection to the server persists until the process is completed. The
entity returned with this response SHOULD include an indication of the request’s current status and
either a pointer to a status monitor or some estimate of when the user can expect the request to be
fulfilled.

203 (Non-Authoritative Information)

The returned metainformation in the entity-header is not the definitive set as available from the origin
server, but is gathered from a local or a third-party copy. The set presented MAY be a subset or
superset of the original version. For example, including local annotation information about the resource
might result in a superset of the metainformation known by the origin server. Use of this response code
is not required and is only appropriate when the response would otherwise be 200 (OK).

204 (No Content)

The server has fulfilled the request but does not need to return an entity-body, and might want to
return updated metainformation. The response MAY include new or updated metainformation in the
form of entity-headers, which if present SHOULD be associated with the requested variant.

If the client is a user agent, it SHOULD NOT change its document view from that which caused
the request to be sent. This response is primarily intended to allow input for actions to take place without
causing a change to the user agent’s active document view, although any new or updated
metainformation SHOULD be applied to the document currently in the user agent’s active view.

The 204 response MUST NOT include a message-body, and thus is always terminated by the first
empty line after the header fields.
