<title>Cache Features Sample</title>
|
|
|
|
<!--
|
|
|
|
This sample demonstrates using an application manifest to store features, html, css and js libraries locally.
|
|
No tiles are stored by this sample in order to keep the code as simple as possible. If you want to see
|
|
how tiles can be stored in the application cache, take a look at the appcache-tiles.html sample.
|
|
|
|
The use cases for using this sample are to ensure you can reload and restart you application
|
|
one it is offline.
|
|
|
|
It is strongly recommended that you use your own optimized build of the ArcGIS API for JavaScript
|
|
using the Web Optimizer: http://jso.arcgis.com/. You can reference the CDN or host it on your
|
|
own web server.
|
|
|
|
Use the included Grunt task to help generate the manifest file. There is manual
|
|
work involved in determining which files need to go into the manifest. The included manifest
|
|
file should work with this sample to give you an idea of what goes into the manifest.
|
|
|
|
A few things to know about manifest files:
|
|
- You cannot load an online url that has a redirect.
|
|
- If there is an error encountered, the manifest file will stop loading
|
|
- The /utils/appCacheManager.js library will auto detect if the manifest changed and
|
|
ask if you want to reload the application.
