Redirect from vaadin application and keep session


I need to solve problem with implementing “e-payment” in the application. There are two main points. The session needs to be still alive, so I can redirect user back to the application. The address bar needs to contain valid url of financial institution and certificate validity information. So setExitUrl(URL) & close(), neither open(ExternalResource) are options [1]

Is there a way how to do this in vaadin? (I don’t care if it will be a new browser window or the same)




Exactly why is not an option?

Best Regards,
