As I mentioned in the bug, the resource can be served with pragma no- 
store. In that case, there will be no expired resource in the cache.

If a hosting service doesn't allow .htaccess or any kind of CGI  
scripts, it's pretty much unsuitable for serving offline applications  
anyway, since one needs a custom content type for the manifest.
