My application is on the example.com domain.
My Keycloak SSO is on the sso.example.com.
I use Keycloak 18.
Is there a way to check the SSO session presence from the same browser, from example.com domain? I need this to decide whether to redirect the user, from example.com to the Keycloak login functionality on sso.example.com in order to re-authenticate them on example.com.
My initial idea was to check the presence of the KEYCLOAK_SESSION cookie, but it is stored under the sso.example.com domain and is not accessible from the example.com application.
