[squid-users] Squid Caching Problem

Hello Squid Users,

i make a LoadBalancing with Squid for a Zope/Plone Cluster. I use icp
and cache_peers for this task. Now I try to cache the static contents
like (css,js,jpg,gif,jpg) from the cache peer. But Squid doesn�t cache.

This is an snippet from my squid.conf

----snip----
http_port 80 vhost
icp_port 3130
cache_peer 127.0.0.1 parent 8080 3131 no-digest no-netdb-exchange
round-robin

# Cache Settings von CacheSetup in CacheFu
acl static_content urlpath_regex -i \.(jpg|gif|png|ico|css|js|doc|pdf|mp3)$
no_cache allow static_content

acl post_requests method POST
no_cache deny post_requests

external_acl_type is_cacheable_type children=20 %{Cookie:__ac}
%{Cookie:;__ac} %{Authorization} %{If-None-Match}
/opt/squid3/etc/squidAcl.py
acl is_cacheable external is_cacheable_type
no_cache allow is_cacheable

no_cache deny all

# Redirect Programm Cache Fu
redirect_program /opt/squid3/etc/iRedirector.py
redirect_children 20
redirect_rewrites_host_header off

refresh_pattern -i \.(jpg|gif|png|ico|css|js|doc|pdf|mp3)$ 60 50% 43200
reload-into-ims
refresh_pattern . 0 20% 4320
...

If i access the squid with a browser i got this in access.log (i have
turned log_mime_hdrs on)

Is it possible to see why squid doesn�t cache anything?
Does anyone have some tips for me?

thx christian
