# Deny CONNECT to other than secure SSL ports
#http_access deny CONNECT !SSL_ports
# Only allow cachemgr access from localhost
http_access allow localhost manager

# web applications running on the proxy server who think the only
# one who can access services on "localhost" is a local user

#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#
# Deny requests to certain unsafe ports

# Deny CONNECT to other than secure SSL ports

# Example rule allowing access from your local networks.

# from where browsing should be allowed
http_access allow localnet
http_access allow server
http_access allow vpnnet
