===== How to Configure Cookie Cache Vary =====
At the bottom of the store, there is a yellow tab that reads **To accept cookies from this site, please click the Allow button below**. By default, the page retrieved from the cache always includes the yellow bar, whether or not the user has clicked **Allow**.

This behavior should vary from user to user, and there are two ways to accomplish this: a javascript-based plugin, and cache vary rewrite rules.

The more efficient option is a javascript-based solution. A javascript plugin would only need to store one copy of the page and would build the display based on the existence of the cookie. If a rewrite rule-based answer is preferred, the site can be configured to vary on the cookie by adding the following rule to your site's .htaccess file:


  RewriteRule .* - [E=cache-vary:user_allowed_save_cookie]
  
When a customer clicks **Allow**, the cookie ''user_allowed_save_cookie=%7B%221%22%3A1%7D;'' will be created. Using the rewrite rule above, the cache will vary on that cookie. This means the cache will store two copies: one that shows the yellow bar at the bottom, and one that does not.
