Sample Response
Response Status: HTTP/1.1 201 Created Response Headers: Transfer-Encoding: chunked Date: Fri, 16 Sep 2011 01:20:22 GMT x-ms-version: 2011-08-18 Server: Windows-Azure-Queue/1.0 Microsoft-HTTPAPI/2.0
Only the account owner may call this operation.
You can specify user-defined metadata as name-value pairs on the queue at the time that it is created.
When a queue with the specified name already exists, the Queue service checks the metadata associated with the existing queue. If the existing metadata is identical to the metadata specified on the Create Queue request, status code 204 (No Content) is returned. If the existing metadata does not match the metadata provided with the Create Queue request, the operation fails and status code 409 (Conflict) is returned. Clients can take advantage of this behavior to avoid an additional call to check whether a named queue already exists.
For guidance about valid queue names, see Naming Queues and Metadata. If the specified queue name is not a valid name, the Create Queue operation returns status code 400 (Bad Request), along with additional error information, as shown in the following example.
HTTP/1.1 400 One of the request inputs is out of range.
