RE: [squid-users] SSLBump and intermedia CA Certificate.

Hi Amos,

I am trying to make the intermediate certs into the dynamic ssl connection.
Based on the code, the "cert" entry of http_port configure is actually a cert chain file. So the configure does have enough info for the intermediate cert chain to work. What is missing is when the SSL_CTX is dynamically generated, it only added the resigned server cert without the chain of certs.

My current difficulty is after I located the dynamic SSL_CTX context, how can I find the resigning cert chain defined in configure line
        http_port ..... cert=certfile....

Is it stored in some global?

Regards,
Ming
