 **Note**: The simple REST data provider expects the API to include a `Content-Range` header in the response to `getList` calls. The value must be the total number of resources in the collection. This allows react-admin to know how many pages of resources there are in total, and build the pagination controls.
 
-```
+```txt
 Content-Range: posts 0-24/319
 ```
 
 If your API is on another domain as the JS code, you'll need to whitelist this header with an `Access-Control-Expose-Headers` [CORS](https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS) header.
