Increase CloudFlare cache times?

[erkyrath]

(Not actually an issue with this repo, but I have to file it somewhere.)

We get 40-50% cache coverage from CloudFlare. We can probably improve that by turning up the cache lifetime.

I originally tried to balance the cache lifetime against the problem of old cache data lingering after a file was replaced. But now the admin tool has a "clear cache" button so this problem is much reduced.

Footnote: should we also add index pages to the cache now? (With a shorter lifetime, say 24 hours.) It would be fairly simple to cache-bump selected index pages when we update them. On the other hand, it would be a giant pain to cache-bump all of them, which we occasionally have to do. (E.g. when changing a web page template.)

This is straightforward for "Enterprise" customers. (Not sure if we are)

We're not.
