Remy is correct when he says that debugging can be a real PITA when you are using a manifest file. A technique I’ve found useful is to monitor your web server logs while running your app to see exactly what resources your browser is requesting.

For example:

1) ssh into your server

2) cd to your log directory (prolly /var/log/httpd/ or /var/log/apache2/)

3) Run: sudo tail -f access_log

4) Reload your app in the browser; your request(s) should pop into the terminal.

When you are done watching the log, press Control-C to quit the tail process.

You can also inspect the ApplicationCache sqlite database manually using sqlite3 at the command prompt (with Safari on Mac, at least – not sure about others).
