Answer 1

in fileupload options there is a url tag which you can use to post to your server method. (this is a .net example)

    $('#fileupload').fileupload({
        url: '@(Url.Content("~/"))controller_name/your_method_name'
    });

and in your method you can get uploaded files like:

var file = Request.Files[i]; // use in for loop
///// do some other thing ///
var filePath = your_path;
file.SaveAs(filePath);
