I've seen differences of opinion across the web on this. It has been said that starting with iOS 5.1, local data storage for HTML5 content on the iPad is no longer guaranteed to be persistent, however on Apple's current Safari developer pages (https://developer.apple.com/technologies/safari/html5.html), offline persistence is suggested to be guaranteed.
Does anyone have any recent experience with this subject and able to comment on how reliable the database features of HTML5 are with Safari on iPad?
