> This issue is reproducible in case when before clicking Sign out you will
> send many requests to server. This can be achieved by switching between
> different application sections that invokes a lot of GET requests.
> I attached two videos one with normal sign out, and one that is showing this
> issue.
> Here is what is happening:
> Click on Sign out button invokes the following request:
> URL: api/v1/logout
> response status code: 200
> After this UI redirects to root of the site (http://HOST_IP:8080/)
> and to understand if we are logged in UI makes the following request:
> URL: api/v1/clusters?fields=Clusters/provisioning_state, the response on this
> request with 403 error will lead us to http://HOST_IP:8080/#/login page, and
> response status 200 we treat as user is logged in and redirect him to
> #/main/dashboard/metrics.
> The root case of this issue is that when we spam server with request and try
> to sign out calling call api/v1/logout, it actually does not logout on server
> because later when we call api/v1/clusters?fields=Clusters/provisioning_state
> we receive response with status 200 like user us still logged in.
> UI hangs later, because when we were doing logout stuff, we dropped different
> properties thinking that we will be logged out. This inconsistency in data
> between UI and wrong server response
> api/v1/clusters?fields=Clusters/provisioning_state leads to such
> unpredictable behavior.
