[Vercel](https://vercel.com/) (and [Next.js](https://nextjs.org/)) both offer the ability to add [Redirects](https://vercel.com/docs/project-configuration#project-configuration/redirects) and [Rewrites](https://vercel.com/docs/project-configuration#project-configuration/rewrites) to your application. This approach is commonly used for subpaths. For example, adding a redirect from `acme.com/old` to `acme.com/new`.

If you want to rewrite `app.acme.com` to `acme.com/app`, you'll need to configure a rewrite making use of the `has` field.

## Configuring a Rewrite with 'has' Field

1. Create a `next.config.js` file is using Next.js or a `vercel.json` file like below.
   
2. Push your changes and redeploy your application.
   

```javascript
rewrites() {
    return {
        beforeFiles: [
            // if the host is `app.acme.com`,
            // this rewrite will be applied
            {
                source: '/:path*',
                has: [
                    {
                        type: 'host',
                        value: 'app.acme.com',
                    },
                ],
                destination: '/app/:path*',
            },
        ]
    }
}
```
```javascript
{
  "rewrites": [
    {
      "source": "/:path*",
      "has": [
        {
          "type": "host",
          "value": "app.acme.com"
        }
      ],
      "destination": "/app/:path*"
    }
  ]
}
```

When a request is made to `app.acme.com`, then it will be rewritten to `acme.com/app`.
