How to use the plupload package with ASP.NET MVC?

Question

I am using plupload version 1.3.0

More specifically how I have to define my controller action to support chunking? Can I use the HttpPosteFileBase as a parameter?

At the moment I am using the following code to initialize the plugin

In the HEAD tag

<link type="text/css" rel="Stylesheet" media="screen" href="<%: Url.Content( "~/_assets/css/plupload/jquery.ui.plupload.css" )%>" />
<link type="text/css" rel="Stylesheet" media="screen" href="<%: Url.Content( "~/_assets/css/plupload/gsl.plupload.css" )%>" />
<script type="text/javascript" src="<%: Url.Content( "~/_assets/js/plupload/gears_init.js" )%>"></script>
<script type="text/javascript" src="<%: Url.Content( "~/_assets/js/plupload/plupload.full.min.js" )%>"></script>
<script type="text/javascript" src="<%: Url.Content( "~/_assets/js/plupload/jquery.ui.plupload.min.js" )%>"></script>

On document ready

$("#uploader").pluploadQueue({
    runtimes: 'html5,html4,gears,flash,silverlight',
    url: '<%: Url.Content( "~/Document/Upload" ) %>',
    max_file_size: '5mb',
    chunk_size: '1mb',
    unique_names: true,
    filters: [
        { title: "Documenti e Immagini", extensions: "doc,docx,xls,xlsx,pdf,jpg,png" }
    ],
    multiple_queues: false
});

Here you go:

[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 Content("chunk uploaded", "text/plain");
}

This method will be called multiple times for each chunk and for each file being uploaded. It will pass as parameter the chunk size and the filename. I am not sure as to whether you could use a HttpPostedFileBase as action parameter because the name is not deterministic.
