HTTP/1.1 200 OK
Vary: Accept,Authorization,Origin
X-Powered-By: Community Solid Server
Accept-Ranges: bytes
Access-Control-Allow-Origin: http://localhost:19000
Access-Control-Allow-Credentials: true
Access-Control-Expose-Headers: Accept-Patch,Accept-Post,Accept-Put,Allow,Content-Range,ETag,Last-Modified,Link,Location,Updates-Via,WAC-Allow,Www-Authenticate
Allow: OPTIONS, HEAD, GET, POST
Accept-Post: */*

But then perform the request a second time and these are the headers:
HTTP/1.1 304 Not Modified
Vary: Accept,Authorization,Origin
X-Powered-By: Community Solid Server
Accept-Ranges: bytes
Access-Control-Allow-Origin: http://localhost:19000
Access-Control-Allow-Credentials: true
Access-Control-Expose-Headers: Accept-Patch,Accept-Post,Accept-Put,Allow,Content-Range,ETag,Last-Modified,Link,Location,Updates-Via,WAC-Allow,Www-Authenticate

Keep-Alive: timeout=5
Notice that there are fewer "link" headers, and most importantly the "storage" header isn't available.
