Don't cache dynamic content (no expires, cache-control or
last-modified). Cache static content (Last-Modified) for 20% of it's age
or at most 3 days.

> refresh_pattern . 3600 20% 14400

Cache dynamic content for 60 hours unless explicitly marked uncacheable.
Static content for 20% it it's age or at most a week.

> refresh_pattern . 3600 50% 14400

Cache dynamic content for 60 hours unless explicitly marked uncacheable.
Static content for 50% of it's age or at most a week.

In all three content with an explicit expiry time (either Expires or
Cache-Control) is expired by what the server says. refresh_pattern only
applies on content not already having an expiry time set (unless you are
using some of the overrides)
