I want to make my OS return 127.0.0.1 on google-analytics.com and
ad.doubleclick.net to speed up the work with Sourceforge.

I put 
127.0.0.1 google-analytics.com
127.0.0.1 ad.doubleclick.net
into /etc/hosts

and checked that /etc/resolv.conf contains
lookup file bind

According to man resolv.conf this should result in /etc/hosts having priority
over the DNS system. However, it simply doesn't work. Both Firefox and the
"host" command behave as if I didn't do anything.

Why doesn't it work when man resolv.conf says it should?
