HTTP status and error codes for XML

The following document provides reference information about the error messages and status codes that are used in the Cloud Storage XML API. For error messages and status codes used by the Cloud Storage JSON API, see this page.

Error Response Format

Cloud Storage uses the standard HTTP error reporting format. Successful requests return HTTP status codes in the 2xx range. Failed requests return status codes in the 4xx and 5xx ranges. Requests that require a redirect returns status codes in the 3xx range. Error responses usually include an XML document in the response body, which contains information about the error.

The following is an example of an error response.

HTTP/1.1 409 Conflict
Content-Type: application/xml
Content-Length: 182
Date: Wed, 03 Mar 2010 00:22:00 GMT
Expires: Wed, 03 Mar 2010 00:22:00 GMT
Cache-Control: private, max-age=0

The following table describes the elements that are in the response body:
