Interface HostnameProvider

All Superinterfaces:
Provider
All Known Implementing Classes:
HostnameV2Provider

public interface HostnameProvider extends Provider
The Hostname provider is used by Keycloak to decide URLs for frontend and backend requests. A provider can either base the URL on the request (Host header for example) or based on hard-coded URLs. Further, it is possible to have different URLs on frontend requests and backend requests. Note: Do NOT use KeycloakContext.getUri() within a Hostname provider. It will result in an infinite loop.
