Options include using the same origin (e.g., `www.example.com/metrics`) or a subdomain (e.g., `metrics.example.com`). Both allow full cookie access, unlike the default provider-hosted domain. Implementing same-origin requires a CDN/load balancer and potential DNS updates, while subdomains only need DNS adjustments. Pre-setup of a server container and tagging server is required.\n"]]
