Telling the authenticated user that he will be redirected
Now, once a user is authenticated, he is redirected to the application with 302 redirect. But the first request to the app may take some time (since a new app session has to be created, or the app doesn't work, and so on) : so the user believes LL::NG is slow, or doesn't work, or lost his request, and he may click again on the button 'connect', or even close the browser and connect again. This may be source of poor user experience and server oveload.
So, it would be nice to make possible to replace the HTTP 302 redirection with a javascript redirection from a page displaying 'Redirection in progress...'
