I'm a bit confused around the 5MB limit that Local Storage provides. Does this include the caching of images and files determined in a manifest file in a HTML5 APP for example?

    Browsers don't have the concept of a "manifest file" for web apps, so I think you have to explain more abut the context. The 5 MB restriction applies to data that is stored via the [`localStorage` interface](https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Storage#localStorage), not to all local data. – Felix Kling Nov 17 '13 at 09:49

    Actually, HTML5 browsers do have a manifest system for offline apps. See [this link](http://diveintohtml5.info/offline.html) –  Nov 17 '13 at 09:52
  • OK, I think this is becoming clearer. localStorage specifies what is stored locally. The caching of such objects like images etc is separate to local storage – user2696536 Nov 17 '13 at 10:42
  • @MikeW: Wow, I didn't know that. Doesn't seem to have anything to do with `lovalStorage` though. – Felix Kling Nov 17 '13 at 10:44

The limit for LocalStorage is different from the limit used for Application Cache. Each browser has a different size, and people have found these values by experimenting with examples. You can have a look at these limits on http://grinninggecko.com/developing-cross-platform-html5-offline-app-1/.

There exists a related StackOverflow question about the limit for Application Cache on Cache Manifest Size Limit and Web Apps.
