[Interest] QNetworkDiskCache + QNetworkRequest::PreferNetwork = always cache

Hi Alexander,

The wording for PreferNetwork in the help is a bit ambiguous:

     "default value; load from the network if the cached entry is older 
than the network entry."

It reads as if a OPTION query has been done, giving "the network entry" 
- but maybe it just relies on the cached page's cache headers.  Are you 
sure that the server is setting an expires timestamp, or max-age correctly?

Hope that helps,
