[Interest] How to overcome QNetworkDiskCache limitation

[Shantanu Tushar]

Hi Thiago,

In your experience what have people done when they have a custom
QNetworkAccessManager subclass whose objects are returned from a
QNetworkAccessManagerFactory? I see from an older post Gianluca made, that
is the exact use-case. Given that the latter's documentation mentions that
it must return a new instance every time, is reimplementing a cache from
scratch the only option? (given that QNetworkDiskCache mentions that it
won't work if its shared across multiple QNetworkAccessManager instances.

Thanks,
