I am trying to set up proxy,but its not configuring properly. I have set my 'Squid.conf' file.I am trying to block 'yahoo' on my nearest machin with IP-address - 192.168.1.58. But though I able to see 'yahoo' page. PFA 'squid.conf' file.

----------------------------
#
# Recommended minimum configuration:
#
acl manager proto cache_object
acl localhost src 127.0.0.1/32
acl localhost src ::1/128
acl to_localhost dst 127.0.0.0/8 0.0.0.0/32
acl to_localhost dst ::1/128

# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed
acl localnet src 10.0.0.0/8 # RFC1918 possible internal network
acl localnet src 172.16.0.0/12 # RFC1918 possible internal network
acl localnet src 192.168.1.0-192.168.1.92 # RFC1918 possible internal network
acl localnet src fc00::/7 # RFC 4193 local private network range
acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines

acl home src 192.168.1.58/255.255.255.0
acl bad url_regex -i yahoo.com
acl good url_regex -i google.com google.co.in

#
# Recommended minimum Access Permission configuration:
#
# Only allow cachemgr access from localhost
http_access allow manager localhost
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
# web applications running on the proxy server who think the only
# one who can access services on "localhost" is a local user
#http_access deny to_localhost

#
# 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
http_access allow Proxy_Port
http_access allow home
http_access allow good
http_access deny bad


# And finally deny all other access to this proxy

# Squid normally listens to port 3128
http_port 3128
http_port 8080 transparent

# We recommend you to use at least the following line.
hierarchy_stoplist cgi-bin ?

# Uncomment and adjust the following to add a disk cache directory.
cache_dir ufs /var/spool/squid 7000 16 256

# Leave coredumps in the first cache dir
coredump_dir /var/spool/squid

# Add any of your own refresh_pattern entries above these.
refresh_pattern ^ftp:       1440    20% 10080
refresh_pattern ^gopher:    1440    0%  1440
refresh_pattern -i (/cgi-bin/|\?) 0 0%  0

squid reads from top to bottom and stops when it hits a match.

and putting in sites 1x1 is tough. I found this example that says it well

create a file listing the bad sites

File: /usr/local/etc/restricted-sites.squid

yahoo.com

This can then be used to always block the restricted sites

AND then IN squid.conf itself Add this to the bottom of the ACL section of squid.conf

acl BadSites dstdomain "/usr/local/etc/restricted-sites.squid"

Add this at the top of the http_access section of squid.conf

http_access deny BadSites`

---END conf

you having

http_access allow localnet at top allows everything

and

acl home src 192.168.1.58/255.255.255.0

should probably either be

acl home src 192.168.1.58/255.255.255.255

or

acl home src 192.168.1.0/255.255.255.0
