[squid-users] Squid-3.3.8: Cant force to cache-hit on this url

Greetings all,

Im having problems with cache hit rates im trying to work out.

I have a complete random URL im concentrating on:
http://performanceforums.com/forums/mgc_cb_evo/clientscript/dojo/dijit/themes/claro/layout/TabContainer.css

No matter what i do, i cannot get this URL to be served from the
cache, it's always a MISS.

Can anyone help me work out why?

I've cut down the squid conf to its most simple required items, with a
ridiculous single refresh_pattern:
-------------------------------------------------------------
debug_options ALL,1 22,5
cache_access_log /var/log/squid3/access.log
cache_log /var/log/squid3/cache.log
cache_store_log /var/log/squid3/store.log
cache_effective_user proxy
cache_effective_group proxy
http_port 3128
cache_replacement_policy heap LRU
maximum_object_size 512 MB
minimum_object_size 0 KB
cache_dir aufs /data/02-1000-DATA/squid 128000 24 128
cache_mem 512 MB
http_access allow all
refresh_pattern . 43200 100% 43200 ignore-private ignore-no-cache
ignore-must-revalidate ignore-reload override-expire override-lastmod
store-stale ignore-auth
-------------------------------------------------------------

Using this to request the URL from Squid:
curl -x 192.168.1.1:3128 --silent -o /dev/null --dump-header
/dev/stdout "http://performanceforums.com/forums/mgc_cb_evo/clientscript/dojo/dijit/themes/claro/layout/TabContainer.css"

Curl output:
