Using the AjaxControlToolKit AjaxFileUpload control (v18.1.1), how can I allow files without an extension to be uploaded? Currently, any file without an extension throws an error. I know there is a default whitelist and the ability to add allowed extensions in the web.config, but it's not clear how to allow files without an extension.

As of v18.1.1, the AjaxFileUpload does not allow uploading of files without an extension in its current state.
