I've just got a rejection from Apple for a web-app I built with Phonegap due to not following Data Storage Guidelines.
In config.xml I've set the "BackupWebStorage" preference to "local" but this doesn't work anymore.
This app doesn't write files on the devices, but it only use some ajax calls and the related JSON object.
What kind of setting I have to use to prevent the backup of any data the app will generate?
