RE: [squid-users] Caching downloaded files from dynamic pages

Thank you for an answer and for the tip, however, that didn't get me far.

I enabled DynamicContent with the instructions, so my squid.conf looks like
this:

---
#caching Fujitsu-Siemens
acl fujitsusiemens dstdomain .fujitsu-siemens.com
cache allow fujitsusiemens
#stop everything else
hierarchy_stoplist cgi-bin ?
acl QUERY urlpath_regex cgi-bin \?
cache deny QUERY 
---
And even though my store.log displays, that it actually saved something
(filesize matches, 1263443 bytes), I cannot find the file and all downloads
from Fujitsu-Siemens are coming from their site, not from squid (=slow and
eating bandwith).
Snap from store.log:

More good hints or ideas what I should try?

This should help a little. Although if they add a UID to the query string
content still may be fetched directly.
