[keycloak-user] Keycloak Gatekeeper Custom Header/Cookie

Hi, I have Keycloak and Keycloak-Gatekeeper set up in OpenShift and it's acting as a proxy for an application. I have successfully configured Gatekeeper to redirect to Keycloak and set the access token correctly. The application that Keycloak Gatekeeper is proxying requires a custom cookie to be set so I figured I could use the Gatekeeper's custom header configuration to set this however I'm running into issues. Configuration looks like: discovery-url: https://keycloak-url.com/auth/realms/MyRealm client-id: MyClient client-secret: MyClientSecret cookie-access-name: my.token encryption_key: MY_KEY listen: :3000 redirection-url: https://gatekeeper-url.com upstream-url: https://app-url.com verbose: true resources: - uri: /home/* roles: - MyClient:general-access headers: Set-Cookie: isLoggedIn=true After re-deploying and running through the auth flow, the upstream URL/application is not receiving the custom header. I tried with multiple headers (key/value) but can't seem to get it working or find where that header is being injected in the flow. Any suggestions/ideas on how to get this working? Thanks, Dan
