+Add's a new `redirectDocument()` function which allows users to specify that a redirect from a `loader`/`action` should trigger a document reload (via `window.location`) instead of attempting to navigate to the redirected location via React Router

+# `redirectDocument`
+
+This is a small wrapper around [`redirect`][redirect] that will trigger a document-level redirect to the new location instead of a client-side navigation.
+
+This is most useful when you have a React Router app living next to a separate app on the same domain and need to redirect from the React Router app to the other app via `window.location` instead of a React Router navigation:
+
+```jsx
+import { redirectDocument } from "react-router-dom";
+
+const loader = async () => {
+  const user = await getUser();
+  if (!user) {
+    return redirectDocument("/otherapp/login");
+  }
+  return null;
+};
+```
+
+## Type Declaration
+
+```ts
+type RedirectFunction = (
+  url: string,
+  init?: number | ResponseInit
+) => Response;
+```
+
+## `url`
+
+The URL to redirect to.
+
+```js
+redirectDocument("/otherapp/login");
+```
+
+## `init`
+
+The [Response][response] options to be used in the response.
