IIRC, refresh patterns are only applicable to objects that don't
return enough information in the headers to determine the freshness
or staleness of an object, i.e. they don't have a LastModified and a
max-age or expires header. So an object with those headers set
wouldn't be affected by a refresh pattern. You can use the override
expires option in the refresh pattern to change that behavior. I may
be wrong, please correct me if I am.
