This problem comes when the browser encounters the manifest line in the html tag, it tries to download the appcache file from the server. But when the server doesn't have this file it returns 404 error, so the application cache goes to OBSOLETE event.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
