safaricfix.js

(function() {
  function sc(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=/';
  }

  function gc(cname) {
    var name = cname + '=';
    var decodedCookie = decodeURIComponent(document.cookie);
    var ca = decodedCookie.split(';');
    var i = 0;
    for(; i < ca.length; i += 1) {
      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 '';
  }

  var is_safari = navigator.userAgent.indexOf('Safari') > -1; // safari detection

  if (is_safari) {
    if (gc('_vsync_cookie') === '') {
      sc('_vsync_cookie', 'true', { expires: 365, path: '/' }); // 1 year
      window.location.replace('!{accountCookieUrl}');
    }
  }
}());
