Ajax file upload in node.js

Want to upload a file using ajax for this using this uploader http://valums.com/ajax-upload/

and in node.js write this code which is working with normal file upload without ajax .

console.log("request " + sys.inspect(req.headers));

            req.on('data', function(chunk) {
              console.log("Received body data:");
              // console.log(chunk.toString());
            });
            var form = new formidable.IncomingForm();

            form.parse(req, function(err,fields, files) {
                console.log('in if condition'+sys.inspect({fields: fields, files: files}));
                fs.writeFile("upload/"+files.upload.name, files.upload,'utf8', function (err) {
                    if (err) throw err;
                    console.log('It\'s saved!');
                    client.putFile("upload/"+files.upload.name, files.upload.name, function(err, res){
                        if (err) throw err;
                        if (200 == res.statusCode) {
                          console.log('saved to s3');

                          httpres.writeHead(200, {'content-type': 'text/plain'});
                          httpres.write('received 1upload:\n\n');
                          httpres.end();
                        }
                    }); 
                });
            });

But this is giving error ?

  'user-agent': 'Mozilla/5.0 (Windows NT 5.1; rv:2.0.1) Gecko/20100101 Firefox/4.0.1',

  origin: 'http://myhost',
  'access-control-request-method': 'POST',
  'access-control-request-headers': 'content-type' }

events.js:45
        throw arguments[1]; // Unhandled 'error' event
                       ^
Error: bad content-type header, no content-type

    at IOWatcher.onReadable [as callback] (net.js:177:10)

I think problem is the content-type is not set in the headers By ajax file upload .thats why this error is coming how can i set the header in this uploader , or how can i make a file in node.js server by incoming data. As it is using the xhr so i think i can't use the formidable.incomingform() what should i use?

Looking at the latest fileuploader.js source code on github he does set the content type

xhr.setRequestHeader("Content-Type", "application/octet-stream");

I believe your problem is elsewhere.
