Jonathan Stark 14 December 2009 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).
