Clearing the application cache for websites that you "Add to your Home screen" on the iPad

Question

The Problem: I have tried just about everything I can think of to clear the cache of a website that has been added to my home screen. Here is what I have tried.

1. Close all running instances of the webapp by double clicking the home screen.
2. Closed all instances of Safari.
3. Removed the webapp from the Home Screen.
4. Settings -> Safari -> Cleared Cache and History.

In Safari, the cache is all cleared and I see the latest version of my web app. However, Once I add it to the home screen, it will display the old version. If i append a '#' to the url it will load only the new html file, however it looks like all the css includes are still cached.

Any ideas? Thanks!

Set the date of your iPad several days to the future and reopen the web app. It then reloads it correctly. After that, you can reset the date to the current date. Very odd, Apple should care about that...

If you are using a cache manifest file, make sure to change something in the .manifest file to trigger a cache refresh.
