+If you want to use Cloudflare or another CDN in front of your Magento store, make sure you turn off the CDN's page cache.

-then you already break your magento store and you should unset all these caches from CloudFlare. Why?
+that is an indication that Cloudflare is breaking your Magento store, and causing undesired behavior. You can fix this by turning off Cloudflare's page cache. Why?
-You will need to understand how Magento works. Magento requires frontend and frontend_cig cookie to be set. Also Magento need form key from each user for the validation process.

-If cloudFlare cache was enabled incorrectly, then you can not get frontend and frontend_cig cookie in the header anymore. Hence all the form_key served from CloudFlare cache will be the same, which will cause Magento validation failure(require different form key from the different user. If user try to add the product to shopping cart or add to compare list, the operation will fail.
+If Cloudflare's page cache is enabled, then you cannot get the ''frontend'' and ''frontend_cig'' cookies in the header anymore, and as such, every ''form_key'' served from Cloudflare's cache will be the same. This causes a Magento validation failure, as a different form key is required from each user. If a user tries to add a product to the shopping cart or to the compare list, the operation will fail.
-The solution is to clean all caches from Cloudflare but only keep media cache if you want to.
+LiteMage is smart enough to handle this situation in its page cache, but Cloudflare and other CDNs are not.
+The solution is to turn off all Cloudflare caching for dynamic content, keeping only static files such as CSS, JS, JPG, PNG, etc. and leave the page caching to LiteMage. The correct header should be:''cache-control: no-store, no-cache''
