local_domain sdsu.edu not working

I'm running Squid 1.0.7 on a Solaris 2.5 system. I first set up
Squid to cache everything. Now I'm attempting to prevent caching
of our local web servers in the sdsu.edu domain. I currently have

        local_domain sdsu.edu

defined in squid.conf, but my access log continues to show:

130.191.17.215 - - [21/Aug/1996:07:50:49 -0700] "GET http://www-rohan.sdsu.edu/graphics/sdsu_signature_1.gif" TCP_HIT 1034
130.191.17.215 - - [21/Aug/1996:07:50:52 -0700] "GET http://libweb.sdsu.edu/images/walking-lbev.gif" TCP_HIT 6294
130.191.17.215 - - [21/Aug/1996:07:50:52 -0700] "GET http://www-rohan.sdsu.edu/graphics/divider_red.gif" TCP_HIT 314
130.191.17.215 - - [21/Aug/1996:07:50:52 -0700] "GET http://www.sdsu.edu/graphics/HOME.gif" TCP_HIT 790

How can I tell if the local_domain definition is doing anything? It shows
up under cachemgr.cgi as defined in the Cache Configuration File.
