@ -232,6 +232,14 @@ For offlineTilesEnablerLayer use this pattern in the constructor:
In the constructor for `offlineTilesEnablerLayer` and in the `extend()` method for `offlineTilesEnabler` is a `state` property. This always defaults to `true`. It's important because it allows you to tell the library at runtime whether the application is online (true) or offline (false) so that the library initializes correctly.
## Working with secure tile services
If you are using a secure tiled map service then you'll need to use the `offlineTilesEnablerLayer` library. There isn't anything special you need to do, the library should automatically recognize you are using a secure service and it will trigger `esri/IdentityManager` if it cannot find valid credentials.
The library manually stores credential information using the following localStorage pattern: `window.localStorage.offline_id_manager`.
If you are using an optimized version of the ArcGIS API for JavaScript make sure you include the `esri/IdentityManager` module.
## Browser storage limitations
Our general guideline for the amount of total storage you can use on a device is be between 50MBs and 100MBs. If you need greater storage than that you'll need to either switch to a hybrid model (e.g. PhoneGap) or use one of our native ArcGIS Runtime SDKs. The Runtime SDKs have fully supported and robust offline capabilities that go beyond what JavaScript is currently capable of.

@ -5,6 +5,8 @@ There are two different libraries for taking tiles offline: `offline-tiles-basic
If you have a requirement for restarting or reloading the app while offline then you should use the advanced library. The `offline-tiles-advanced-min.js` library lets you create a custom basemap layer that extends TiledMapServiceLayer.
If you have a requirement for using token-based security on your tiled map service then you'll need to use this library.
##O.esri.Tiles.OfflineTileEnablerLayer
The `offline-tiles-advanced-min.js` library provides the following tools for working with tiled map services. This library is designed for both partial and full offline use cases, and it will work if you have a requirement for browser reloads or restarts while offline.
