I've got things seemingly working. However, I visited several youtube videos, it seems that no videos are caching. I've set the video download threshold to be 1.
The videocache log does seem to contain many things, only the reloaded piece. There are completely nothing new under /var/spool/videocache.
I've done update-vc already.
Squid did not crash or anything.
videocache config (1.9.6)
squid config (3.1.9)
