Configure squid to ignore some sites
If you are using squid like me, it is sometimes useful to avoid cacheing some internet addresses. To accomplish this you could edit your /etc/squid/squid.conf file and add the following line
acl NOCACHEDOMAIN dstdomain www.vg.no no_cache deny NOCACHEDOMAIN
This makes it possible to view www.vg.no without viewing a squid cached page.
