Transfer large amount of data between webview and titanium

Hi,

I have some legacy jQuery code which is running in a Titanium WebView. The code is handling a large amount of data (~2-6MB) which I want to cache. We have tried the following options but all failed:

1. Local Storage: Size is limited to 5 MB on iOS
2. HTML5 File API: No support for iOS and Android
3. Sending data as part of Titanium Event: The data gets truncated when the event is received by the Titanium app

Is there any other way I can transfer such amount of data from my webview to my Titanium code so that I can save it in my native filesystem?

Thanks in advance!
