问题 In a Chrome App I am able to access requests made by the <webview> and I am able to redirect if needed. The problem is the web app rendered inside the <webview> tag registers a service worker and lots of requests are handled by the service worker. Based on my tests the onBeforeRequest won't be notified.

问题 I'mm working on a service worker, who should just cache some specific files. But after implementation and refresh (yes I enabled "dumb sw after reload") there are much more files "loaded via the sw" then I added in the "files to cache" list. I'm new with the service worker and have no idea what is wrong. I just followed some tutorials about it. Here the code.
