self cache website for offline html5

I have built a html5 gallery which does work offine but what I need help with is getting the app to detect if the user is online and if so will update the mainifest when the user opens up the app.

Firstly, you need to make sure that the manifest file isn't listed in the manifest file as this will prevent it from being re-fetched even if the user is online.

Once you have done this, if you set cache-mode to prefer-online it will re-fetch the pages when a connection is available. If you only want to update the manifiest, you don't need to do this step, most user agents will re-fetch the manifest when a connection is available as long as it is not included in its own listing.

You can also force it using the JavaScript API:

window.applicationCache.update()

You can see this example and lots more details of the JavaScript API here.
