Hi,

I'm using WebView2 version 124.0.2478.109. My WebView2 is registered to a custom requestType (named "ProvideFile") and Source property is set to an external app's Uri. When the WebResourceRequested event fires up, the external App is able to get all the Bundle Files by which WebView2 can run the correctly the hosted web app. All works fine, no problem.
By design I know that all the files provided by the external app are always the same. So I'd like to avoid to claim those files each time. In other words I'd like to get them from the browser cache starting from the second time I claim them.

How can I force cache usage when all the application's bundle file are provided by WebResourceRequested mechanism?

I'll appreciate any help you can provide,
