HI! Amos Problem has been resolved, Now the client can access the HTTPS website by squid proxy. That reason is the iptables rules don't allow TCP port 443; After i create one rules to allow tcp port 443 the client pc can visit https website! Thank you very much! -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/squid-3-1-10-https-visit-bug-tp4666203p4666212.html Sent from the Squid - Users mailing list archive at Nabble.com.
