Squid acts correctly with this page, because the pages from (at the one you mentioned) are not cacheable.
The page contains a Last-Modified: header, but the webserver is configured
to return the CURRENT date/time of the server as the LM-value
(Date: and Last-Modified: header are the same).
This makes the pages uncacheable, because squid calculates the value "0"
as the TTL and releases the page (IMHO).
I REALLY hate webmasters who hack there server to act like this. :-(

Maybe it would be a good idea to modify squid to check for such a
case and use the default TTL instead of the calculated TTL...
