Response.url 属性是独立的

Cache API 缓存 Response 时不会改变其中的内容:
caches.open('text').then(async c => {
const r = await fetch('/home');
await c.put(new Request('/test'), r);
const res = await c.match('/test');
await c.put(new Request('/test1'), res);
const res1 = await c.match('/test1');
console.log(res1.url);
});
