Example code for my blog post http://out-println.appspot.com/posts/offline_example.

Browser support

• Firefox: all tests pass. However, I've sometimes observed erratic behavior when testing manually: the offline cache stops updating, I have to clear it and restart the browser;
• Chrome: all tests pass, but I get random errors in the Selenium tests (where DOM elements seem to be uninitialized) ;
• Safari: same as Chrome, but the errors happen much more often.

Running

Install the Play! framework as explained here.

To run the application, type play run --%prod in the application's root directory.

To run the unit tests, type play test, navigate to http://localhost:9000/@test and click the 'Run all' link.

Reading the code

If you're new to Play!, this should get you started:

• conf/routes maps URIs to controller methods (controllers are in app/controllers);
• when a controller calls render(), the corresponding template in app/views is invoked.

For more information, refer to the Play! documentation.
