Cross origin request blocked

[LinusSee]

When using the navbar-plugin and navigating back and forth via the browser a cross origin request occurs and is blocked.
The problem occurs, when the applications are deployed under different resources.
If app1 is deployed under "localhost:4001" and app2 under "localhost:4002" and you try to navigate from app2 back to app1 via the browser, he sends requests to the server with the URI of app2, even though he routed back to app1.
