It also includes examples of tracking progress, configuring concurrency and part size and handling failures.It does say with respect to browser uploads that 'In order to support large file uploads in the browser, you must ensure that your CORS configuration exposes the ETag header; otherwise, your multipart uploads will not succeed. See the guide for more information on how to expose this header.' Possibly the CORS configuration may also need to allow more methods than listed in the 'Configuring CORS' section of the example you linked.
