aggressive caching of intranet content

I have build a small intranet solution and use it with intranet plugin. In WebApp everything work fine - but in deskapp I can not update content due to aggressive Caching. Even if I close desktop and login again, there is still the cached content.

Who can i force deskapp to refresh? (from inside my intranet-app)

greetings
Matt

@mdoehle There’ s an option to clear the cache from the DeskApp tray icon
