Cross-Origin Resource Sharing (CORS) is a specification that defines how browsers and servers communicate across origins by using HTTP headers, such as those assigned by Object Storage API requests. The Object Storage API supports these headers. For more information, see www.w3.org/TR/access-control/.
Access-Control-Allow-Credentials
Access-Control-Allow-Methods
Access-Control-Allow-Origin

You can assign these headers to only objects.
Example 1.8. Assign CORS header request: HTTP
This example assigns the file origin to the
Origin header, which ensures that
the file originated from a reputable source:
PUT $publicURL/{container}/{object} HTTP/1.1
Host: storage.clouddrive.com
X-Auth-Token: eaaafd18-0fed-4b3a-81b4-663c99ec1cbb
