# useRequestHeaders
> Use useRequestHeaders to access the incoming request headers.
You can use built-in [`useRequestHeaders`](/docs/4.x/api/composables/use-request-headers) composable to access the incoming request headers within your pages, components, and plugins.
```ts
// Get all request headers
const headers = useRequestHeaders()
// Get only cookie request header
const { cookie } = useRequestHeaders(['cookie'])
```
In the browser, `useRequestHeaders` will return an empty object.
## Example
We can use `useRequestHeaders` to access and proxy the initial request's `authorization` header to any future internal requests during SSR.
The example below adds the `authorization` request header to an isomorphic `$fetch` call.
```vue [app/pages/some-page.vue]
```
