plupload with ASP.NET forms authenticated handler
原标题:

I am trying to use plupload to upload files in ASP.NET. My upload handler ideally needs to be included in the forms authentication on my site, but it doesn t work in this case. I can t see the request that plupload makes in firebug, and don t really understand what its doing. Is there any way to get around this problem?

Here is my plupload initialisation code:

$(function () {
    $("#uploader").pluploadQueue({
        runtimes:  gears,flash,silverlight,browserplus,html5,html4 ,
        url:  /Handlers/UploadImage.ashx ,
        filters: [
            { title: "Image files", extensions: "jpg,gif,png" },
            { title: "Zip files", extensions: "zip" }
        ],
        flash_swf_url:  /Scripts/plupload/plupload.flash.swf ,
        silverlight_xap_url:  /Scripts/plupload/plupload.silverlight.xap 
    });

I had flash set as the first runtime in my list, and this was what was being used. Flash has a bug in it (http://bugs.adobe.com/jira/browse/FP-1044), which causes any existing cookies and authentication (digest/basic) information to be discarded when doing FileReference.upload. plupload has a flag to force flash to use URLStream instead of FileReference.upload. Setting this to true fixes the problem I was having. :)
