function getCookie(cname) {
    var name = cname + "=";
    var decodedCookie = decodeURIComponent(document.cookie);
    var ca = decodedCookie.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) {

// Data to store
var LastReportGenerated="Jul 11 2013",
// Get the top level domain and assign as .domain.com
baseDomain = '.cssjunction.com', //your domain must be in format of '.domain.com' – dot and root domain
// Set Expires (optional)
expireAfter = new Date();
expireAfter.setDate(expireAfter.getDate() + 7); //setting up  cookie expire date after a week

// Now setup cookie
document.cookie="Report={'ReportName':'MainReport', 'lastGenerated':" + LastReportGenerated + "}; domain=" + baseDomain + "; expires=" + expireAfter + "; path=/"; // 'path=/'' always. If you don’t setup your path=/, auto path will be saved as from where the cookies is being saved hence it wont be accessible across any subdomain.
