The NetCache parent does not provide any date/modification/expiry time
on the reply. It should have send at least a Date header, but preferably
a Last-Modified header as well as the FTP server is capable of
indicating the modification time.

If you uncomment the recommended refresh_pattern settings for FTP then
the objects should be cached for one day I think. (a little bit unsure
what would happen if there is no date information at all as in the above
NetCache generated reply..)
