Adding to homescreen for iPad won't save to cache.

I have noticed a problem with the "add to home screen" selection when I want to save the app to my iPad as a standalone app/link.  It will not work offline, and when I go online, it re-downloads the app all over again.  I looked on the net for this problem with Html5 and it does not appear to be a problem with my iPad settings, but a problem within the apps code.  The app needs to have the cache information changed to "cache.manifest".  Can this be setup in the builder?  How will this be implemented for each app I want to test?
