This mode allows us to test the HTTP disk cache with two mechanisms: 1. If RequestServer is launched with --http-disk-cache-mode=testing, it will cache requests with a X-Ladybird-Enable-Disk-Cache header. 2. In test mode, RS will include a X-Ladybird-Disk-Cache-Status response header indicating how the response was handled by the cache. There is no standard way for a web request to know what happened with respect to the disk cache, so this fills that hole for testing. This mode is not exposed to users.
