How do you redirect a root domain to a www. subdomain in Deno Deploy?
To redirect a root domain to a www subdomain in Deno Deploy, you can use a middleware function in your server script to check the request URL and redirect to the www subdomain if necessary. Here's an example code snippet to get you started:

```
import { Application, Router } from https://deno.land/x/oak/mod.ts;

const app = new Application();
const router = new Router();

// Middleware function to redirect root domain to www subdomain
app.use((ctx) => {
  const { host, path, protocol } = ctx.request.url;
  if (host === yourdomain.com) {
    ctx.response.redirect(`${protocol}://www.yourdomain.com${path}`);
  }
});

// Add your routes here
router.get(/, (ctx) => {
  ctx.response.body = Hello, World!;
});

app.use(router.routes());
app.use(router.allowedMethods());

await app.listen({ port: 80 });
```

Make sure to replace `yourdomain.com` with your actual domain name.
