[application meta-information]
Date: Wed, 06 Oct 2010 23:27:03 GMT
Server: CAStor Cluster/5.0.0
[content-stream]
This response means the node to which the request was sent is returning the requested content in
the message body of the response.

5.3.3. Other Normal READ Responses

This section shows other normal READ responses, which apply to both named and unnamed
objects.
HTTP/1.1 206 Partial
Content Date: Wed, 1 Sept 2010 15:59:02 GMT
Server: CAStor Cluster 5.0.0
Content-Length: 500
[ application-meta-information ]
CRLF
[ content-stream ]
When a READ request includes one or more
Storage includes only the requested bytes range(s). In this case, instead of returning a 200 OK
response, DX Storage returns a 206 Partial Content response, indicating that only part of the stored
stream is being returned. The application-meta-information and content-stream are the same as in
the preceding example.
HTTP/1.1 301 Moved Permanently
Date: Wed, 1 Sept 2010 15:59:02 GMT
Server: CAStor Cluster/5.0.0
Location: http://cluster-ip/name-or-uuid?auth=2096EFA659295BBB819D1FECCE77D2EF
Content-Length: 0
The preceding response means the requested stream has been located, but another node in the
cluster will supply the content. Furthermore, all future requests of this DX Storage cluster should be
made through the new access node until another 301 response is received. There is no message-
body, so the content length is always 0. The value of the Location header indicates which node in
the cluster the redirect should go to. The client is expected to send another READ request using the
exact URI contained in the Location header.
HTTP/1.1 307 Temporary Redirect
Date: Wed, 1 Sept 2010 15:59:02 GMT
Server: CAStor Cluster/5.0.0
Connection: close
Location: http://cluster-ip/name-or-uuid?auth=2096EFA659295BBB819D1FECCE77D2EF
Content-Length: 0
The preceding response is similar to the 301 response, except the client should continue to use the
current node (the one generating this response) for future requests until further notice.

5.4. Error Responses to READ

The DX Storage cluster can return the following responses when the specified content cannot be
found or there is a problem with the READ request itself.
