Consider an application that asks the user for authentication creds. These are stored in a static var in the slot's for authentication required signal.

However, there is no way to change the values provided by the slot once the auth creds had been accepted for once, since the provuide auth signal will nbever be fired again.

To really be useful, the QNAM object must also present a non evented API, to set creds and clear them.

The docs mention something about:
QNetworkRequest::AuthenticationReuseAttribute

However, for the life of me, I couldn't make any sense and figure out how this incorporates into clearing the creds so they'd be asked through the signal for the next time HTTP auth is needed. I thought a long the lines of setting to manual, and then setting to automatic again. But then I will need to know if the auth succeded and do more juggelry that would be ugly and un-natural.

I will revert to delete the QNAM object and reinstnatiate it until this is fixed.
