Answer 1

From my experience with getting a site working offline on the iPad:

• The name of the file needs to end with .manifest
• The mime type needs to be text/cache-manifest
• Have a version in the comments of your manifest
• Create some javascript functions using window.applicationCache... to check if the browser sees a change in the manifest and to reload the content, also capture the status events and display them somewhere
