Squid

Why doesn't squid block access to sites?

Tell me why squid is not blocking traffic?
I need to configure it so that access only works for the whitelist, but first I want to disable everything (to make sure it works). But squid doesn't block anything. Why?

# Recommended minimum configuration:

# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed

acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines

# Recommended minimum Access Permission configuration:
#

# Only allow cachemgr access from localhost
http_access allow localhost manager
http_access deny manager

# Deny requests to certain unsafe ports
http_access deny !Safe_ports

# Deny CONNECT to other than secure SSL ports
http_access deny CONNECT !SSL_ports

# We strongly recommend the following be uncommented to protect innocent

# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS

# Example rule allowing access from your local networks.
# Adapt localnet in the ACL section to list your (internal) IP networks
# from where browsing should be allowed
#http_access allow localnet
http_access allow localhost

# And finally deny all other access to this proxy
#http_access allow Pupkin SitesWarez

#http_access allow all
acl whitelist dstdomain .ubuntu.com wiki.squid-cache.org
#http_access allow whitelist

http_access deny all

# Squid normally listens to port 3128

# Uncomment the line below to enable disk caching - path format is /cygdrive/, ie
