squid reverse proxy not caching!

I set up squid as a reverse proxy for apache on the same host. Things
seem to be working fine except the access log shows everything is a
TCP_MISS. It's running on port 3128 and apache on port 80 until I can
get things straightened out.

OS: CentOS 5
Squid: squid-2.6.STABLE6-5.el5_1.2

(Why was this so easy in 2.5 and so hard in 2.6?)

Below are the differences from default in the squid.conf file. Any
suggestions?

[root@myhost squid]# grep -A 3 '!!!' squid.conf
#!!!
