HTML5 Local Storage URL Prefix

I am using local storage for self-educational purposes and checking an checkbox if it is checked and closing the Bootstrap Modal.

$( "#olurmu" ).click(function() {
    var isaret = document.getElementById("olurmu");
    localStorage.setItem("olurmu", isaret.checked);
});

function isaretKontrol() {
    if(localStorage.getItem("olurmu"))
    {
        var evet = localStorage.getItem("olurmu");
        document.getElementById("olurmu").checked = evet;
    }
}

The problem is localSotrage is working on www.mydomain.com but the thing is it is not working when i go to http://ift.tt/1AQSREp. Is there any way store the localstorage file all through my domain?
