-===== How to handle cookie cache very =====
+===== 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:
-A site needs to be varying on cookie "user_allowed_save_cookie". When user click "Allow" cookie, it will insert  "user_allowed_save_cookie=%7B%221%22%3A1%7D;" to browser. So, it requires adding a rewrite rule to make the cache varying on that cookie. The cache needs to store two copies: one showing the yellow bar at the bottom while the other one without it.
-Add the following rewrite rules to .htaccess
   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.
-Alternatively, most people use javascript based plugin and there is no need to set cache vary as above.  The better option is to use a different cookie law plugin, then javascript will do the display based on cookie set.
