I am using SWFUpload to do file uploading in a ASP.NET MVC 1.0 website. It is working fine, but I am not able to authenticate the upload method. The HttpContext.User.Identity.Name returns an empty string. I am assuming this is because the Flash movie is making the post. I am also using the wrapper provided here: http://blog.codeville.net/2008/11/24/jquery-ajax-uploader-plugin-with-progress-bar/.

The controller action below gets fired, but as mentiond above the user object is not passed.

Any help is appreciated!

View

HTML

            <form enctype="multipart/form-data" method="post" action="/Media/Upload/Photo">
                <input type="file" id="userPhoto_Photo" name="userPhoto_Photo" />
            </form>

Javascript

    $(function() {
        $("#userPhoto").makeAsyncUploader({
            upload_url: '/Media/Upload',
            flash_url: '<%= Url.Content("~/Content/Flash/swfUpload-2.2.0.1.swf") %>',
            file_size_limit: '1 MB',
            file_types: '*.jpg; *.png; *.gif',

            button_action: SWFUpload.BUTTON_ACTION.SELECT_FILE, 
            button_width: 210,
            button_height: 35, 
            button_image_url: '<%= Url.Content("~/Content/Images/UploadPhoto.png") %>',
            button_text: '',
button_cursor: SWFUpload.CURSOR.HAND,
button_window_mode: SWFUpload.WINDOW_MODE.TRANSPARENT

        });
    });   

Controller Action

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult Upload()
    {
        if (Request.Files.Count == 1)
        {
            //Upload work
        }
        return RedirectToAction("Index", "Profile");
    }
