Session time out handling


I am working on a Vaadin project. Can any one help me understanding following items?

How is session time out managed in Vaadin?
User may spend more than 30 minutes by editing some content in the webpage without making any explicit server call. Will a session time out happens if there is no explicit server call. If it happens, how can I extend session time out by handling user actions on the page
