Minor Description
If I request a 57 MB file TS caches the fill no problem and on subsequent requests the file gets served from cache. If I cut the request early, about 40MB downloaded and I have proxy.config.http.background_fill_completed_threshold = 0.5 and proxy.config.http.background_fill_active_timeout is suitably high, the file is not cached. I am of the understanding that the background fill values should keep the OS connection open and allow the full item to be cached though this is not happening.
I have tried various values for proxy.config.http.background_fill_completed_threshold ranging from 0.0 -> 0.5, none seem to work.
