Re: [squid-users] Re: https bypass squid cache in reverse proxy mode

Hi Amos,

Thank you for your response.

The following is is my configuration:

http_port 80 accel defaultsite=www.abc.com
cache_peer 202.x.x.x parent 80 0 no-query originserver name=myAccel
acl our_sites dstdomain www.abc.com
cache_peer_access myAccel allow our_sites
cache_peer_access myAccel deny all

acl HTTPS proto HTTPS
deny_info http://www.efg.com/ HTTPS
http_access deny HTTPS

cache_peer 75.x.x.x parent 80 0 no-query originserver name=myserver1
acl sites_myserver1 dstdomain www.efg.com

I change my host file in window and connect to http://www.efg.com is
no problem and can see the log in /var/log/squid3/access.log.

But when i click one of the icon in this site is involved https, no
response and I can see any a hit in the log.

I know i can use https_port 443 to add the cert in squid. But I want
to config this squid server to serve different customers as a cache
server and their dns porint to this server. What I want to do is:

1. Cache the http service for different site ( now is OK)
2. if this site involve https service, let the traffice redirect to
the original web server ( no solution now).
3. if https_port can support multiple cert for different sites. cache
the https sites. (no solution now).

Hope you can help.

Regards,
Gary
