<div>{{APIRef("Fetch")}}</div>
<p>{{domxref("Response")}} 接口的 <strong><code>redirect()</code></strong> 方法返回一个可以重定向到指定 URL 的 <code>Response</code> 。</p>
<div class="note">
<p><strong>Note</strong>: 主要和 <a href="/en-US/docs/Web/API/ServiceWorker_API">ServiceWorker API</a> 有关。 A controlling service worker could intercept a page's request and redirect it as desired. This will actually lead to a real redirect if a service worker sends it upstream.</p>
