no caching of LAN pages?

I am using squid Version 2.2.STABLE4, and I have to avoid caching of the
LAN pages. I've read the mailing list archive and found about the no_cache
directive, but it seems it's not working. The machine acts as a
transparent proxy, so there is a cisco which routes all the http requests
to it; the request arrive all right, they are processed and the cache
works fine, but it caches everything. I checked the ACL with the debug
option and it's used correctly. Here is my squid.conf file... does anybody
understand what I'm missing? :-)

thanks

Eugenia
