I am trying to do ajax delete with jquery but getting http error 400.

I was searching and I've seen that there is some problems with delete method in jquery.

$.ajax({

url: 'additions/cancelUpload',

type: 'DELETE',

data: {filename : ui.draggable.get(0).file.name},

success: function (res) {

alert(res);

}

});

execution does not passed here:

@RequestMapping(value = "cancelUpload", produces="text/html")

@ResponseBody

public String cancelUpload(@RequestParam("filename")String filename, HttpSession session ){

...

}
