我发现问题似乎与浏览器配置有关。
我在这里潜水了：

1. 打开Internet Explorer 9


2. 点击


3. 在顶部切换到隐私权标签，然后点击高级按钮。


4. 允许第一方Cookie和第三方Cookie并启用会话Cookie。

你能确认我没有什么能做，但最多警告我的用户？

it seems I'm not able to set a cookie on IE9 and I don't understand the cause. My goal is to set a cookie which expires after a year, and I'm using the following code

$.cookie( name, value, { expires:days } )

where days is equal to 365. The cookie I've got is gone as soon as the session expired ( i.e. close and open the browser ) I've also tried with the following code but nothing changed

function setCookie( name, value, days ) {
    var exdate=new Date();
    exdate.setDate(exdate.getDate() + days);
    var c_value = value + ( ( days==null ) ? "" : "; expires="+exdate.toUTCString() + "; path=/");
    document.cookie=name + "=" + c_value;
}

Is there something IE9 doesn't like (e.g. some characters)? Please give me a hand with this stuff.

Best Regards MB

I found that the problem seems to be tied to the Browser configuration. I've got a dive here:

1. Open Internet Explorer 9
2. Click on the Tools icon on the very right at the top and then on Internet Options.
3. At the top switch to the tab Privacy and click on the Advanced button.
4. Allow First-Party Cookies and Third-Party Cookies and enable Session Cookies.

All works fine now.

Could you confirm that there is nothing I can do about it but warn my users at most?
