### Upload Progress ([.kt][UploadProgressKotlin], [.java][UploadProgressJava])

Upload a file to a server (for example, Imgur) and report progress as the request body is being written. You can implement a ProgressListener to receive updates and wrap the original request body with ProgressRequestBody. This allows you to monitor how many bytes have been uploaded and calculate the percentage of completion.

    String SUPPORTED_UPLOADED_JS_EXTENTIONS = "supported.uploaded.js.extentions";

    /** The key of the configuration. e.g. css */
    String SUPPORTED_UPLOADED_CSS_EXTENTIONS = "supported.uploaded.css.extentions";

    /** The key of the configuration. e.g. jpg,jpeg,gif,png,swf */
    String SUPPORTED_UPLOADED_MEDIA_EXTENTIONS = "supported.uploaded.media.extentions";

}

// ListMultipartUploadsHandler - GET Bucket (List Multipart uploads)
// -------------------------
// This operation lists in-progress multipart uploads. An in-progress
// multipart upload is a multipart upload that has been initiated,
// using the Initiate Multipart Upload request, but has not yet been
// completed or aborted. This operation returns at most 1,000 multipart
// uploads in the response.
