Hi there,

how to make file upload via jQuery AJAX work? I tried almost everything but I always get a 400 error. There is no example/documention on that topic available. This is my current guess: 

var files = e.target.files;
var data = new FormData();
data.append('upload', files[0]);
$.ajax({
    url: 'upload',
    type: 'POST',
    data: data,
    processData: false,
    contentType: 'multipart/form-data'
});

Thank you
