Thank you for your reply; there is nothing about SSL neither in iptables nor in squid settings now. It only intercepts port 80 requests.. There is nothing visible in squid's access.log nor the firewall logs of the server when I click on an image to download in Whatsapp. -turgut _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
