/**
 * <p>Sets the <code>cors</code> configuration for your bucket. If the configuration exists,
 *          Amazon S3 replaces it.</p>
 *          <p>To use this operation, you must be allowed to perform the <code>s3:PutBucketCORS</code>
 *          action. By default, the bucket owner has this permission and can grant it to others.</p>
 *          <p>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
 *             <code>http://www.example.com</code> to access your Amazon S3 bucket at
 *             <code>my.example.bucket.com</code> by using the browser's <code>XMLHttpRequest</code>
 *          capability.</p>
 *          <p>To enable cross-origin resource sharing (CORS) on a bucket, you add the
 *             <code>cors</code> subresource to the bucket. The <code>cors</code> 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. </p>
 *          <p>When Amazon S3 receives a cross-origin request (or a pre-flight OPTIONS request) against a
 *          bucket, it evaluates the <code>cors</code> configuration on the bucket and uses the first
 *             <code>CORSRule</code> rule that matches the incoming browser request to enable a
 *          cross-origin request. For a rule to match, the following conditions must be met:</p>
 *          <ul>
 *             <li>
 *                <p>The request's <code>Origin</code> header must match <code>AllowedOrigin</code>
 *                elements.</p>
 *             </li>
 *             <li>
 *                <p>The request method (for example, GET, PUT, HEAD, and so on) or the
 *                   <code>Access-Control-Request-Method</code> header in case of a pre-flight
 *                   <code>OPTIONS</code> request must be one of the <code>AllowedMethod</code>
 *                elements. </p>
 *             </li>
 *             <li>
 *                <p>Every header specified in the <code>Access-Control-Request-Headers</code> request
 *                header of a pre-flight request must match an <code>AllowedHeader</code> element.
 *             </p>
 *             </li>
 *          </ul>
