Qt 6.3.0 - Is the QtWebEngine object able to manage the display in offline mode?

[morikann]

Hello everyone,

I am developing a Qt application displaying a WebEngineView.

The cache is working properly.

I would like to go further by integrating an offline mode:
without a network, the application must display the web page based on its cache (like the standard process of a browser like Chrome).
For now, despite setting the QWebEngineProfile, QQuickWebEngineProfile and QWebEngineSettings objects, the page displays: "No internet ... ERR_INTERNET_DISCONNECTED"

Does anyone know or have implemented this feature before?

Thank you in advance for your answers.

Qt version: 6.3.0
