Is it possible to make the Cloudflare CDN use different cache entries based on a cookie value?
More specifically, can I put a cookie that has
theme=light and get a different cached response from the CDN than if I have theme=dark?3 Replies

Thanks!
you should do theming client side
then you can get the benefit of caching and not pay the pricey plan
