CloudFlare doesn't proxy HTML pages, by default, because so many of them are dynamically generated. You have to add a page rule to proxy HTML too.

Thanks. I was actually under the impression that CF would do HTML as well, but I searched and you seem to be right: https://support.cloudflare.com/entries/22036831-How-do-I-cac... So I'll try that out and see if it helps performance/bandwidth.
