 * `method` Method to use when POSTing chunks to the server (`multipart` or `octet`) (Default: `multipart`)
 * `testMethod` HTTP method to use when chunks are being tested. If set to a function, it will be passed a FlowFile and a FlowChunk arguments. (Default: `GET`)
 * `uploadMethod` HTTP method to use when chunks are being uploaded. If set to a function, it will be passed a FlowFile and a FlowChunk arguments. (Default: `GET`)
+* `allowDuplicateUploads ` Once a file is uploaded, allow reupload of the same file. By default, if a file is already uploaded, it will be skipped unless the file is removed from the existing Flow object. (Default: `false`)
 * `prioritizeFirstAndLastChunk` Prioritize first and last chunks of all files. This can be handy if you can determine if a file is valid for your service from only the first or last chunk. For example, photo or video meta data is usually located in the first part of a file, making it easy to test support from only the first chunk. (Default: `false`)
 * `testChunks` Make a GET request to the server for each chunks to see if it already exists. If implemented on the server-side, this will allow for upload resumes even after a browser crash or even a computer restart. (Default: `true`)
 * `preprocess` Optional function to process each chunk before testing & sending. Function is passed the chunk as parameter, and should call the `preprocessFinished` method on the chunk when finished. (Default: `null`)
