#Sample configuration of squid proxy below:

http_port 192.168.0.1:3128
cache_mem 20MB
cache_dir_ufs /var/spool/squid 2000 16 256
chae_access_log /var/log/squid/access.log

http_access allow our_host1

Restriction Web Access By Time:
# Add this to the bottom of the ACL section of squid.conf
acl home_network src 192.168.1.0/24
acl business_hours time M T W H F 9:00-17:00
# Add this at the top of the http_access section of squid.conf
http_access allow home_network business_hours
Or, you can allow morning access only:
# Add this to the bottom of the ACL section of squid.conf
acl mornings time 08:00-12:00
# Add this at the top of the http_access section of squid.conf
http_access allow mornings

Restricting Web Access By IP Address:
You can create an access control list that restricts Web access to users on certain networks. In this case, it's an ACL that defines a home network of 192.168.1.0.
# Add this to the bottom of the ACL section of squid.conf
acl home_network src 192.168.1.0/255.255.255.0

You also have to add a corresponding http_access statement that allows traffic that matches the ACL:
# Add this at the top of the http_access section of squid.conf
http_access allow home_network
