## Examples ##

Plain old JS:

    function setCookie(name,value,days) {
      if (days) {
        var date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        var expires = "; expires="+date.toGMTString();
      }
      else var expires = "";
      document.cookie = name+"="+value+expires+"; path=/";
    }

    function getCookie(name) {
      var nameEQ = name + "=";
      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,c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
      }
      return null;
    }

    function deleteCookie(name) {
      setCookie(name,"",-1);
    }


## Considerations ##

* Cookies impact performance:
    * Cookies are sent with every request.
        * So if the image has 50 images, it gets sent 50 times...
        * Hence why Google Page Speed or Yahoo's YSlow recommend sending static content from different, cookie-free, domains.
    * Consider using the Cookie path feature if you can't reduce the size.
