you may even even add

always_direct allow !bf

in order not to query it for other file types

if you do not use always|never_direct the thing will not work correctly

I am not sure if talking back|front-end cache is good here, lets stay with
large_object and small_object cache

we suppose here that the small_object cache is the one exposed and used by
your users

if you do not use always|never_direct in the small_object cache you probably
never get a hit and the small_object cache will pull the large objects
without storing them ever since you limit it with max_object_size

means you need to force calling the large_object cache which then should
 store the object and you get a hit at the next call

this is pretty confusing
