Hi all,

I am trying to configure squid as a interception HTTPS proxy under CentOS 7. At every https request, I am receiving a certificate error.

My current config for squid is:

I have tried disabling "sslproxy_cert_error" and "sslproxy_flags" directives, without luck.

Any ideas about what am I doing wrong?

Thanks.

Do you have a copy of the Root CA you are using to re-encrypt the SSL stream installed in the browser?

Hey There,

I think it would be better asked at squid-users list: - http://www.squid-cache.org/Support/mailing-lists.html#squid-users - squid-users@lists.squid-cache.org
