easy:SetOpt_Proxy_IssuerCert(file)
This option makes sense only when used in combination with the
#CURLOPT_PROXY_SSL_VERIFYPEER
option. Otherwise, the result of the
check is not considered as failure.
A specific error code (#CURLE_SSL_ISSUER_ERROR
) is defined with the option,
which is returned if the setup of the SSL/TLS session has failed due to a
mismatch with the issuer of peer certificate
(#CURLOPT_PROXY_SSL_VERIFYPEER
has to be get too for the check to
fail).
