I need to prevent any application caching by the browser in my TouchKit application.
Here’s some code that I thought would do the trick:
public class MyServlet extends TouchKitServlet {
@Override
protected void servletInitialized() throws ServletException {
super.servletInitialized();
TouchKitSettings s = getTouchKitSettings();
s.getApplicationCacheSettings().setCacheManifestEnabled(false);
s.getApplicationCacheSettings().setOfflineModeEnabled(false);
}
}
However, this does not seem to work. If I look at on the Safari debugger either on a Mac or iPhone, I see an Application Cache called safari.manifest that is signficant in size. I’ve tried to use the annotations @CacheManifestEnabled(value=false) and @OfflineModeEnabled(value=false) also with the same result. The only way that I can prevent the browser from storing this cache information is by putting it into Private browsing mode, which is a hard sell for my users.
Is this a bug or am I doing something wrong?
