| 42 <B>DESCRIPTION</B> | |
| 43 Sets the Cross-Origin Resource Sharing (CORS) configuration on one or more | |
| 44 buckets. This command is supported for buckets only, not objects. The | |
| 45 cors-xml-file specified on the command line should be a path to a local | |
| 46 file containing an XML document with the following structure: | |
| 47 | |
| 48 <?xml version="1.0" ?> | |
| 49 <CorsConfig> | |
| 50 <Cors> | |
| 51 <Origins> | |
| 52 <Origin>http://origin1.example.com</Origin> | |
| 53 </Origins> | |
| 54 <Methods> | |
| 55 <Method>GET</Method> | |
| 56 </Methods> | |
| 57 <ResponseHeaders> | |
| 58 <ResponseHeader>Content-Type</ResponseHeader> | |
| 59 </ResponseHeaders> | |
| 60 </Cors> | |
| 61 </CorsConfig> | |
| 62 | |
| 63 The above XML document explicitly allows cross-origin GET requests from | |
| 64 http://origin1.example.com and may include the Content-Type response header. | |
| 65 | |
