Use an application state object (it is session scoped), so on your login page
you could have:
@ApplicationState
private UserStateTracker stateTracker;
@InjectPage
private Home homePage;
Object onActivate(){
if(stateTracker.isSignedIn()){
//user is already signed in so redirect
return homePage;
}
}
If you need something slightly more complex (i.e.:filtering per request) then
you need to implement a request filter and do the checking there:
public class PageAccessController implements RequestFilter {
public PageAccessController(ApplicationStateManager asm) {
asm_ = asm;
}
public boolean service(Request request, Response response,
RequestHandler handler) throws IOException {
UserStateTracker stateTracker = asm_.get(UserStateTracker.class);
if(!stateTracker.isSignedIn())
//user is not signed in so redirect him to the login page
}
}
You also will need a contribution in your AppModule:
public static void contributeRequestHandler(
OrderedConfiguration<RequestFilter> configuration,
@InjectService("TimingFilter") RequestFilter filter,
@InjectService("PageAccessController") RequestFilter
pageAccessController) {
configuration.add("Timing", filter);
configuration.add("PageAccessController", pageAccessController,
"before:PageRender");
}

Subject: Redirect before page render
Hi,
I have a Login page, and user will navigate to, say, Work page after
success authenticate process.
But when an authenticated user access Login page, I wish to just
redirect to Work page.
How can I do that?
Allex J.
