I'm not sure what do "a specific service" and "squid-wide" mean.
I think Alex Rousskov already solved my issue in this thread: shared 
memory cache can't hold responses with a "Vary" header.
Thank you anyway.

My goal was figuring out why Squid with Rock always send TCP_HIT instead 
of TCP_MEM_HIT for some responses (turned out they have "Vary" header).
