( I'm sorry that this was my third message for the same question to the list. b/c the before two messages sent from yahoo got lost...) Hello members, I want to set squid, which accepts https from clients, then forward the request to original server with http protocal. This is the setting I considered: https_port 443 accel vhost cert=/squid/etc/xxx.crt key=/squid/etc/xxx.key protocol=http cache_peer 10.0.0.1 parent 80 0 no-query originserver name=origin_1 acl service_1 dstdomain .xxx.com cache_peer_access origin_1 allow service_1 Then I access to squid with this way: https://www.xxx.com/ Can squid accept this https request and forward it to original server with http correctly? btw, what's the usage of "protocol=http"? I can't understand for it enough. Thanks in advance.
