// Spec: https://wicg.github.io/private-network-access/#cors-preflight
//
// These tests verify that PNA preflight responses are cached.
//
// TODO(https://crbug.com/1268312): We cannot currently test that cache
// entries are keyed by target IP address space because that requires
// loading the same URL from different IP address spaces, and the WPT
// framework does not allow that.
