[squid-users] Almost objects don't cached (reverse proxy squid 3.1)

Hello Squid Users.~

My squid.conf below.

---------------------------------------------------------------------------------------------------------------------------
http_port 80 vhost
https_port 443 accel cert=/etc/squid/a.crt key=/etc/squid/a.pem
cafile=/etc/squid/a.ca protocol=https

cache_peer 1.1.1.1 parent 80 0 no-query originserver name=my_parent
no-digest no-netdb-exchange
acl s1_domain dstdomain img.test.com
http_access allow s1_domain
cache_peer_domain my_parent img.test.com
http_access deny all

# We recommend you to use at least the following line.
hierarchy_stoplist cgi-bin ?

# Uncomment and adjust the following to add a disk cache directory.
cache_dir ufs /cache 36000 16 256

# Add any of your own refresh_pattern entries above these.
refresh_pattern ^ftp: 1440 20% 10080
refresh_pattern ^gopher: 1440 0% 1440
refresh_pattern . 1440 50% 2880 reload-into-ims

I make script like this : curl -O/dev/null http://img.TEST.com/aaaaaaaa.gif
But almost object do not store in cache_dir and that connect the
Origin server directly
I ran the script twice , same result. ( some object was cached )
I want to store all object in my disk and prevent to code (304 or 200)
at Origin server

And I have wonder what is mean about "TCP_REFRESH_UNMODIFIED"

How can I do ?

Thank you for reading this :-)

PS.

In STORE.LOG. almost of object was RELEASE.
