I'm running `XMLHttpRequest` request like this:

```
var data = JSON.stringify({
    name : "123",
    id : 12
});

window.console.log("Submitting: " + data);
var req = new XMLHttpRequest();
req.open('POST', "http://localhost/index.php/lorem/ipsum", true);
req.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
req.onreadystatechange = function() {
    if (  req.readyState==4) {
        window.console.log( "Sent back: " + req.responseText );
    }
}
req.send(data);

```

as you can see there's no name for parameter being passed.

now I want to read that JSON data inside `ipsum` function of `lorem` controller.
How can I do this? `$this->input->post();` returns false :(
