My application is load balanced on BigIP F5 and authentication by Keycloak. I have created BigIP F5 VIP as client in keycloak with web origin as *. I am able to successfully authenticate users and logout too when accessed in single tab but with multi tab i am facing CORS issues.
Here are the steps to reproduce:
User logs into application in one tab(tab1). After successful login opens another tab(tab2), user logs out from the application from tab2.
Then user tries to continue accessing app from tab1, CORS issue on Preflight request to keycloak is observed.
Setup : User —> Application(client) —> BigIP Apm —> Keycloak
weborigin url for BigIP Apm client in keycloak as *
Could you please help me fix this scenario
