Using plupload with MVC3

Question

So, I\'ve implemented plupload using flash runtime in MVC3.

It works perfectly, in the sense that it uploads using the correction Action and runs it all. However, I\

Answer 1

The following has worked for me:

[HttpPost]
public ActionResult Upload(int? chunk, string name)
{
    var fileUpload = Request.Files[0];
    var uploadPath = Server.MapPath("~/App_Data");
    chunk = chunk ?? 0;
    using (var fs = new FileStream(Path.Combine(uploadPath, name), chunk == 0 ? FileMode.Create : FileMode.Append))
    {
        var buffer = new byte[fileUpload.InputStream.Length];
        fileUpload.InputStream.Read(buffer, 0, buffer.Length);
        fs.Write(buffer, 0, buffer.Length);
    }
    return Json(new { message = "chunk uploaded", name = name });
}

and on the client:

$('#uploader').pluploadQueue({
    runtimes: 'html5,flash',
    url: '@Url.Action("Upload")',
    max_file_size: '5mb',
    chunk_size: '1mb',
    unique_names: true,
    multiple_queues: false,
    preinit: function (uploader) {
        uploader.bind('FileUploaded', function (up, file, data) {
            // here file will contain interesting properties like 
            // id, loaded, name, percent, size, status, target_name, ...
            // data.response will contain the server response
        });
    }
});

As far as the bonus question is concerned I am willing to answer it by don't use sessions, as they don't scale well, but because I know that you probably won't like this answer you have the possibility to pass a session id in the request using the multipart_params:

multipart_params: {
    ASPSESSID: '@Session.SessionID'
},

and then on the server perform some hacks to create the proper session.
