- Inherit from QNetworkAccessManager and reimplement createRequest so
that it modifies the QNetworkRequest parameter's cache attribute to
the value you want and then calls the original implementation.
- Implement your own QDeclarativeNetworkAccessManagerFactory that
instantiates your QNetworkAccessManager inherited class and tell the
declarative engine to use it
(QDeclarativeEngine::setNetworkAccessManagerFactory)
