req=ReadFile(“myfile.txt”) used to work (Offlineapp.manifest) before going to PWAs with the ServiceWorker. With extraFiles containing the name of the text file upon a full deploy to the server this file can be seen in the Application/Cache Storage when running Chrome on a PC. It’s there along with all of the other picture files used by the app and those work properly when offline. Is there some other method to use for reading these cached files?
I also tried req=Ajax("myfile.txt’), no luck.
