Squid transparent proxy (Yahoo messenger/Gmail/https not works) help !!!

[Yogesh Patil]

Hello,
      I am using SQUID 2.6.STABLE17 with fedora core 8, & BIND
DNS SERVER configured on the same box, i have configured squid as
transparent proxy with all default settings , and applied iptables
rule by using the following
command

iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT
--to-port 3128

      so the problem is that i am able to browse websites very well,
but Gmail, Yahoo Messenger, MSN Messenger etc.. and all the websites
using https not works, what would be the issue ?

Regards,
