[squid-users] squid accelerator always requests peer to refresh

I configured Squid (3.0 STABLE7) in web accelerator mode to speed up a slow dynamic website.

Now all img and css files are completely served by squid. They don't show up on the slow machine 10.1.1.2. But the dynamic content itself always (page reload, other clients) leds to a request to the slow machine:

--- 8< ---
1225483916.728 444 10.1.1.254 TCP_REFRESH_MODIFIED/200 8889 GET http://www.mydomain.de/test.html - FIRST_UP_PARENT/10.1.1.2 text/html
1225483917.113 0 10.1.1.254 TCP_IMS_HIT/304 283 GET http://www.mydomain.de/img/pic.gif - NONE/- image/gif
--- >8 ---

Even with all the http-standard violating options for refresh_pattern that I used (config see below).

The expected result should be that the slow machine only receives requests once within 30 min. Is something wrong in my config or what is your suggestion?

-------- squid.conf ----------

http_port 10.1.1.1:80 accel defaultsite=www.mydomain.de vhost
cache_peer 10.1.1.2 parent 80 0 no-query originserver

cache_mgr cacheproblem_at_mydomain.de

# restrict access
acl okdomains dstdomain www.mydomain.de mydomain.de
http_access allow okdomains

acl cache urlpath_regex \?
never_direct allow cache

refresh_pattern . 10 80% 30 override-expire override-lastmod ignore-reload ignore-no-cache ignore-no-store ignore-private

url_rewrite_host_header off

# cache tuning

Thanks,
