[Moo] Link Cancel Request

[Sid-ahmed D]

Hello world, 

I need your help, please ^^

3 requests are started by function "form_comment(x)" but just one can 
running.
I try to use link cancel but doesn't work.

"div" name is a primordial element and it can change depending on page.

form_comment(div1);
form_comment(div1);
form_comment(div1);

form_comment = function(id){
    new Request.JSON({
                url: '/echo',
        data: $(id),
        link: 'cancel',
               onRequest: function() {},
               onComplete: function (json) {}    
            }
        }).send();
};

Could you please help me ?
