DELETE request Ajax in a Floodlight SDN controller

Question

I have a function in my JavaScript that makes an Ajax request to the REST interface of a Floodlight controller.

function excluir(nome)
{
    var jsonExclui = ("{" + '"name": "'+nome+'" }');
    alert(jsonExclui);
    $.ajax(
    {
        url: "http://192.168.56.99:8085/wm/staticflowpusher/json",
        method: "DELETE",
        //  type: 'DELETE',
        data: jsonExclui,
        dataType: "json",
        success: function(data)
        {
            alert(data.status);
        },
        error: function(data)
        {
            alert("Deu erro : "+data.status);
        }
    });
}

The DELETE method is accepted and appears in the SDN controller documentation.

But when analyzing the browser console realized he tells me that I'm sending OPTIONS and not DELETE.

Remote Address:192.168.56.99:8085 Request URL:'http:192.168.56.99:8085/wm/staticflowpusher/json' Request Method:OPTIONS Status Code:405 Method Not Allowed

Accept-Ranges:bytes Allow:DELETE, POST Connection:keep-alive Content-Type:application/json Date:Thu, 14 May 2015 11:46:43 GMT Server:Restlet-Framework/2.3.1 Transfer-Encoding:chunked

There is some method to make the browser do not do this pre-request OPTIONS?
