Hola Folks .
i have been trying to optimise caching website that is http and has many images in its content like cnn.com <http://cnn.com/>
and trying to cache https static website like https://www.alwatanvoice.com <https://www.alwatanvoice.com/>
i have squid enabled with https and i installed certificates on clients pcs :
i have been fighting to have better HIT ration but it is vey poor .
i hope someone give me a hand and focous on caching images contents of the 2 websites below .
here is what i have in my config file :

# Recommended minimum Access Permission configuration:
#
# 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
# Only allow cachemgr access from localhost
http_access allow localhost manager
http_access deny manager
# 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
http_access deny all
# Squid normally listens to port 3128
