[squid-users] Facebook URL username can't block

Hi,

I've strange problem here whereis my configuration:

squid.conf
acl urlpathdeny urlpath_regex -i "/usr/local/etc/squid/urlpath.deny"
http_access deny urlpathdeny

urlpath.deny:
3gp\.exe$

That's rules work to block 3gp.exe file, but I try to block facebook
URL pattens like this:

http://www.facebook.com/foo

I put "foo" in urlpath.deny but doesn't work. Base on access.log:

1368853169.627 1575 192.168.100.90 TCP_MISS/200 83947 GET
http://www.facebook.com/foo - DIRECT/69.171.237.20 text/html

Anyone have a clue to this problem? Thank any suggestions.
