javascript - Does the number of expired cookies count in MAX nb of cookies allowed per domain -

i know each browser has limit (see here) on number of cookies allowed domain.

are expired cookies taken account in limit?

ex: let's chrome limits 150 cookies per domain. domain example.com has set in computer 140 cookies expired. can example.com set 20 more cookies ?

my app deals app. each time user loads deal page (example : deal 'sony mp3), modal show showing information specific deal. load info when user loads first time. if user reloads page, modal not show up.

so if/when user loads page of deal (ex: amazon kindle), have create cookie (called example cookie_deal_id367).

as user can maybe go hundreds of deals every year, wonder what's limit. it advised not go beyond 50, wonder if play on expiration , set few days (duration deals last for), , way, if number of expired cookies not taken account browsers when set 50 cookies limit, succeed in want implement.

open ideas this, or better way.

my current code:

 $(window).load(function(){     if ($.cookie("cookie_deal"+deal_id) == null) {       $.cookie('cookie_deal"+deal_id, 'yes', { expires: 720, path: '/' }); // show  modal once per deal       $("a.modal:first").trigger("click");            }   });
