According to the losas there is not actually a squid in front of the
launchpad deployment of loggerhead at this time.

We should test it, but to me it seems reasonable to cache static
things for a day or more, and to cache all generated pages for at
least a few minutes. We'd just need to check that if the user
refreshes the page that does cause it to be revalidated.
