    Question Squid to Allow Certain HTTPS Websites


    Hello,

    I want some help from you all to enhance my squid server configuration. So far I did some work to strengthen my proxy server. I want to allow some https URLs, only those; while the following configurations are also there, what should I add to my squid.conf file? My conf file is as follows

    Code:
    #
    # Recommended minimum configuration:
    #
    acl manager proto cache_object
    acl localhost src 127.0.0.1/32 ::1
    acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1
    
    # 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 192.168.101.0/24	# 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 SSL_ports port 443
    acl Safe_ports port 80		# http
    acl Safe_ports port 21		# ftp
    acl Safe_ports port 443		# https
    acl Safe_ports port 70		# gopher
    acl Safe_ports port 210		# wais
    acl Safe_ports port 1025-65535	# unregistered ports
    acl Safe_ports port 280		# http-mgmt
    acl Safe_ports port 488		# gss-http
    acl Safe_ports port 591		# filemaker
    acl Safe_ports port 777		# multiling http
    acl CONNECT method CONNECT
    
    #
    # 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
    
    # And finally deny all other access to this proxy
    acl groupA src 192.168.101.13 192.168.101.60 192.168.101.66 192.168.101.93
    192.168.101.18 192.168.101.59 192.168.101.72 192.168.101.107
    192.168.101.79 192.168.101.48 192.168.101.243 192.168.101.47
    192.168.101.49 192.168.101.62 192.168.101.70 192.168.101.73
    acl groupB src 192.168.101.65 192.168.101.180 192.168.101.36
    192.168.101.40 192.168.101.14 192.168.101.52 192.168.101.116
    # reply_body_max_size 10 MB groupA
    acl business_hrsA time 07:00-08:45
    acl business_hrsB time 13:00-14:00
    acl business_hrsC time 11:30-12:30
    acl business_hrsD time 14:00-15:00
    #acl AllowedSites dstdomain "/etc/squid/sitesallowed.squid"
    acl permited dstdomain "/etc/squid/allsites"
    http_access allow localnet groupA business_hrsA
    http_access allow localnet groupA business_hrsB
    http_access allow localnet groupB business_hrsC
    http_access allow localnet groupB business_hrsD
    http_access allow localnet permited
    http_access deny all
    
    # Squid normally listens to port 3128
    http_port 3128
    
    # 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 512 16 256
    
    # Leave coredumps in the first cache dir
    coredump_dir /var/spool/squid
    visible_hostname [my.proxy]
    # 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
    refresh_pattern .		0	20%	4320
    With the above configuration users can access https site during allocated time slots but when the time is expire they can't access https sites

    I'm using squid 3.1 version on CentOS
