What's the simplest cross-browser way to do allow a web site user to do multiple file picking and uploading with "Negotiate" and/or basic authentication? Although I am not too worried about IE6, I do need to support IE8, Firefox, Safari, Opera, and Chrome; ideally, I would support mobile browsers too.
- Using a Flash uploader such as SWFUpload or Flajaxian seems to work in IE8, but authentication is apparently broken/not supported in the POST request generated by Flash in Firefox or Chrome (it always sends anonymous requests).
- Using HTML5 to do multi-file picking would be great, but wouldn't support IE8 or IE9.
- Out of ideas.
Thanks.
