    Flash error when uploading through a proxy

    Hi, 
    We are having a problem when uploading multiple files through a proxy. Some of the files in the queue are uploaded and then the proxy credentials are demanded by the browser. If I hit cancel, the following error shows up:
    Flash: The upload task is interrupted! http 407 
     
    I'm using flash, the problem doesn't happen with iframe and I cannot test with silverlight.
    Reproduced using the online demo:
    AjaxUploader version: 3
    Flash version:  10
    IE version: 8
     
    Any idea what the problem may be? 
     
    Thanks,
    Igor
