200 |
OK |
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;
- HEAD the entity-header fields corresponding to the requested resource are sent in the response without any message-body;
- POST an entity describing or containing the result of the action;
- TRACE an entity containing the request message as received by the end server.
|
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 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 persist 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.
|
205 |
Reset Content |
The server has fulfilled the request and the user agent SHOULD reset the
document view which caused the request to be sent. This response is primarily
intended to allow input for actions to take place via user input, followed by
a clearing of the form in which the input is given so that the user can
easily initiate another input action. The response MUST NOT include an entity.
|
206 |
Partial Content |
The server has fulfilled the partial GET request for the resource. The request
MUST have included a Range header field indicating the desired range, and MAY
have included an If-Range header field to make the request conditional.
The response MUST include the following header fields:
-
Either a Content-Range header field indicating
the range included with this response, or a multipart/byteranges
Content-Type including Content-Range fields for each part. If a
Content-Length header field is present in the response, its
value MUST match the actual number of OCTETs transmitted in the
message-body.
-
Date
-
ETag and/or Content-Location, if the header would have been sent
in a 200 response to the same request
-
Expires, Cache-Control, and/or Vary, if the field-value might
differ from that sent in any previous response for the same
variant
If the 206 response is the result of an If-Range request that
used a strong cache validator, the response SHOULD NOT include
other entity-headers. If the response is the result of an
If-Range request that used a weak validator, the response MUST
NOT include other entity-headers; this prevents inconsistencies
between cached entity-bodies and updated headers. Otherwise,
the response MUST include all of the entity-headers that would
have been returned with a 200 (OK) response to the same request.
A cache MUST NOT combine a 206 response with other previously
cached content if the ETag or Last-Modified headers do not
match exactly.
A cache that does not support the Range and Content-Range headers MUST NOT
cache 206 (Partial) responses.
