Container for the parameters to the PutCORSConfiguration operation.
This operation is not supported by directory buckets.
Sets the cors
configuration for your bucket. If the configuration exists,
Amazon S3 replaces it.
To use this operation, you must be allowed to perform the s3:PutBucketCORS
action. By default, the bucket owner has this permission and can grant it to others.
You set this configuration on a bucket so that the bucket can service cross-origin
requests. For example, you might want to enable a request whose origin is http://www.example.com
to access your Amazon S3 bucket at my.example.bucket.com
by using the
browser's XMLHttpRequest
capability.
To enable cross-origin resource sharing (CORS) on a bucket, you add the cors
subresource to the bucket. The cors
subresource is an XML document in
which you configure rules that identify origins and the HTTP methods that can be executed
on your bucket. The document is limited to 64 KB in size.
When Amazon S3 receives a cross-origin request (or a pre-flight OPTIONS request) against
a bucket, it evaluates the cors
configuration on the bucket and uses
the first CORSRule
rule that matches the incoming browser request to
enable a cross-origin request. For a rule to match, the following conditions must
be met:
The request's Origin
header must match AllowedOrigin
elements.
The request method (for example, GET, PUT, HEAD, and so on) or the Access-Control-Request-Method
header in case of a pre-flight OPTIONS
request must be one of the AllowedMethod
elements.
Every header specified in the Access-Control-Request-Headers
request
header of a pre-flight request must match an AllowedHeader
element.
For more information about CORS, go to Enabling Cross-Origin Resource Sharing in the Amazon S3 User Guide.
