Create Dynamic pages

Hi,

In vaadin book mention that there is a way for creating dynamic web pages overriding getWindow method. So is that a efficient way for do that ?
Or there is another way called Urifragmentation . What is the efficient way ?

Are you refererring the chapter 11.2.2 of book of vaadin? Using the UriFragmentUtility might at least feel more efficient than using a not fragment based urls for dynamic page creation since it doesn’t reload the entire web page when the fragment is changed.
