Details

(Whiteboard: [necko-triaged])

A theory on DNS cache use is that most cache entries are used while very young, so expiring older entries that haven't expired is not that bad. Getting data on this will help us determine how effective the current DNS cache is and if we should change the default DNS cache size.
