@zirain can you confirm if a URL like `https://gateway.envoyproxy.io/tasks/observability/grafana-integration/` will redirect to `https://gateway.envoyproxy.io/v1.0.2/tasks/observability/grafana-integration/` ? this will impact the URL in the browser, so anyone adding these links in other places...

@zirain one issue with the redirect approach is, it negatively impacts SEO, so ideally prefer if something like `https://gateway.envoyproxy.io/tasks/observability/grafana-integration/` can return the current docs (v1.0.2 in this case) w/o changing...

Some more prior art [haproxy-ingress](https://haproxy-ingress.github.io/docs/configuration/keys/#auth-external) [gloo](https://docs.solo.io/gloo-edge/latest/guides/security/auth/extauth/) [traefik](https://doc.traefik.io/traefik/middlewares/http/forwardauth/) [ambassador](https://www.getambassador.io/docs/edge-stack/latest/howtos/ext-filters) [nginx](https://kubernetes.github.io/ingress-nginx/examples/customization/external-auth-headers/) [envoy](https://www.envoyproxy.io/docs/envoy/latest/api-v3/extensions/filters/http/ext_authz/v3/ext_authz.proto) [contour](https://projectcontour.io/docs/v1.24.1/config/client-authorization/) [istio](https://istio.io/latest/docs/tasks/security/authorization/authz-custom/) [envoy-gateway](https://gateway.envoyproxy.io/v1.0.0/user/security/ext-auth/)

needs to be fixed upstream ?
