   *   sent to the origin server the cookie encodes, for the duration of the cookie
   *   and as long as the origin server remains healthy. If the cookie has expired or
   *   the origin server is unhealthy, then a new origin server is calculated and
   *   used.
   * - `"ip_cookie"`: Behaves the same as `"cookie"` except the initial origin
   *   selection is stable and based on the client's ip address.
   * - `"header"`: On the first request to a proxied load balancer, a session key
   *   based on the configured HTTP headers (see
   *   `session_affinity_attributes.headers`) is generated, encoding the request
   *   headers used for storing in the load balancer session state which origin the
   *   request will be forwarded to. Subsequent requests to the load balancer with
   *   the same headers will be sent to the same origin server, for the duration of
   *   the session and as long as the origin server remains healthy. If the session
   *   has been idle for the duration of `session_affinity_ttl` seconds or the origin
   *   server is unhealthy, then a new origin server is calculated and used. See

   *   pool using the Cloudflare PoP location for proxied requests or the location
   *   determined by `location_strategy` for non-proxied requests.
   * - `"least_outstanding_requests"`: Select a pool by taking into consideration
   *   `random_steering` weights, as well as each pool's number of outstanding
   *   requests. Pools with more pending requests are weighted proportionately less
   *   relative to others.
   * - `"least_connections"`: Select a pool by taking into consideration
