Cookies are not saved after reboot

[karpiyon]

Hi,

I create an extension and I use the functions below to store and restore my panel coockies.

All is working well, even when I close PS and open start it again.

However, asfter rebooting my PC the the coockies are not saved.

Actually I'm not sure it is because of a restart but they do disappear.

My querations are:

What can delete my coockies? Are they related to specific extention and where are they stores?

Perhaps there is a 3rd party app which deletes/clean them?

I have latest win10 with latest PS installed

function setCookie(cname, cvalue, exdays) {
    var d = new Date();
    d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000));
    var expires = "expires=" + d.toUTCString();
    document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";
}//setCookie

function getCookie(cname) {
    var name = cname + "=";
    var ca = document.cookie.split(';');
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') {
            c = c.substring(1);
        }
        if (c.indexOf(name) == 0) {
            return c.substring(name.length, c.length);
        }
    }
    return "";
}
