Fastly-specific property - obtain the IP address used for the request
Undefined for user-created responses and when the response is returned from the cache. Set cacheOverride: new CacheOverride("pass") to ensure a value.
Fastly-specific property - Obtain the port used for the request

(that awaited that response) will show as hits.
Undefined if the environment does not support the new HTTP Cache hostcalls.
Fastly-specific property - Returns whether the cached Response is considered stale.
Undefined if the environment does not support the new HTTP Cache hostcalls.
