Hi gentlemen,
I'm trying to cache youtube videos following
http://wiki.squid-cache.org/Features/StoreID guide.
But seems like squid rejects to cache the content because original
server returns header 'Cache-control:private' and 'refresh pattern ...
ignore-private' doesn't take effect. Here is debug log entries that are
interesting here (I think):

Squid version is squid-3.4.0.1-20130910-r12989.
So my questions are:
1) Am I right that refresh_pattern ... ignore-private should work here
and help to cache reply with CC:Private?
2) Is there another (may be more correct) way to force squid to cache
replies with CC:Private?
3) How can I check that 'refresh_pattern' config string is parsed
correctly and all options are remembered by squid?
TIA,
Pavel
