HTTP Status Code 207 - MULTI-STATUS

A Multi-Status response conveys information about multiple resources in situations where multiple status codes might be appropriate.

The default Multi-Status response body is a text/xml or application/xml HTTP entity with a 'multistatus' root element. Further elements contain 200, 300, 400, and 500 series status codes generated during the method invocation. 100 series status codes SHOULD NOT be recorded in a 'response' XML element.

Although '207' is used as the overall response status code, the recipient needs to consult the contents of the multistatus response body for further information about the success or failure of the method execution. The response MAY be used in success, partial success and also in failure situations.

The 'multistatus' root element holds zero or more 'response' elements in any order, each with information about an individual resource. Each 'response' element MUST have an 'href' element to identify the resource.

A Multi-Status response uses one out of two distinct formats for representing the status:

1. A 'status' element as child of the 'response' element indicates the status of the message execution for the identified resource as a whole. Some method definitions provide information about specific status codes clients should be prepared to see in a response. However, clients MUST be able to handle other status codes, using the generic rules defined in RFC2616 Section 10.

2. For PROPFIND and PROPPATCH, the format has been extended using the 'propstat' element instead of 'status', providing information about individual properties of a resource. This format is specific to PROPFIND and PROPPATCH, and is described in detail in RFC4918 Section 9.1 and RFC4918 Section 9.2.

The message body that follows is an XML message and can contain a number of separate response codes, depending on how many sub-requests were made.

HTTP Status Code: 200 - Ok

The request has succeeded. The 200 (OK) status code indicates that 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 instead. For CONNECT, no payload is allowed because the successful result is a tunnel, which begin...

HTTP Status Code 401 - Unauthorized

Although the HTTP standard specifies "unauthorized", semantically this response means "unauthenticated". That is, the client must authenticate itself to get the requested response. The request has not been applied because it lacks valid authentication credentials for the target resource. The server generating a 401 response MUST send a WWW-Authenticate header field containing at least one challenge applicable to the target resource. If the request included authentication credentials, then the 401 response indicates that authorization has been refused for those credentials. The user agent MAY repeat the request with a new or replaced Authorization header field If the 401 response contains the same challenge as the prior response, and the user agent has already attempted authentication at least once, then the user agent SHOULD present the enclosed representation to the user, since it usually contains relevant diagnostic information. The request requ...

HTTP Status Code 304 - Not Modified

This is used for caching purposes. It is telling to client that response has not been modified. So, client can continue to use same cached version of response. A conditional GET or HEAD request has been received and would have resulted in a 200 OK response if it were not for the fact that the condition evaluated to false. If the client has performed a conditional GET request and access is allowed, but the document has not been modified, the server SHOULD respond with this status code. The 304 response MUST NOT contain a message-body, and thus is always terminated by the first empty line after the header fields. The response MUST include the following header fields: If a clockless origin server obeys these rules, and proxies and clients add their own Date to any response received without one, caches will operate correctly. 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 t...
