Large File uploading to asp.net MVC

I need a way to upload large files (600 mb to 4 gb) in an asp.net mvc website.
Currently I am using swfupload; it works well enough, but it is a huge hit on the webserver because it sends it in one big upload, plus I have to set it in the web.config to allow that huge of a file, which is a huge security risk. In the past when I was doing web forms development I used Neatupload which breaks up the file into chunks and uploads them individually. I am looking for a way to upload large files in mvc that uploads via chunking it up. Any ideas on how I could do this?

Method 1

Silverlight File Upload

Method 2

I ended up using Darren Johnstone’s ASP.NET File Upload Module to handle the uploading on the server side. Though I modified it slightly so that it could take a guid on the querystring that it would save the temp file to that guid name.

It was nice because it saved the file as it arrived at the server, and stripped the file out of the posted data which it then sends to the action on the controller that was specified.

Method 3

Example in my view:

<input id="FileGUID" name="FileGUID" type="hidden" value="f632c00b-9b66-4716-8075-79df63b780fb" />
    <input type="file" id="FileUpload1" name="fileUpload1" />

    <script type="text/javascript">
        var UploadUrl = '/Video/AsyncUpload?FileGUID=f632c00b-9b66-4716-8075-79df63b780fb';
        $(function() {
            $("#FileUpload1").makeAsyncUploader({
                upload_url: UploadUrl,
                flash_url: '/Content/Flash/swfupload.swf',
                button_image_url: '/Content/Images/blank-button.png',
                button_text: '<font face="Helvetica, Arial" size="13pt" color="#ffffff">Upload File</font>',
                disableDuringUpload: 'input[type="submit"]',
                file_size_limit: '8024 MB',
                button_text_top_padding: 2
            });
        });
    </script>

Then in the actual save action for this page I look for a file where the asyncupload action would have saved the file based on the FileGUID

Method 4

A SignalR implementation example can be found here.

This also includes functionality for working with HttpContext.Request.GetBufferlessInputStream(), which allows you to begin working with the post data before it’s fully uploaded.
