OCSP validation via AIA responders through a proxy
I'm finding conflicting information on whether OpenSSL can perform OCSP validation via AIA responders through a proxy. An open issue at GitHub suggests that this is an open feature request (https://github.com/openssl/openssl/issues/6965), however I've seen people saying that a proxy can be specified when using "openssl ocsp" by passing "-host <proxy_host>:<proxy_port>" and "-path <OCSP_AIA_URL>". Which one is correct?
If context matters, this is about having support in stunnel for performing OCSP validation via AIA responders through a proxy. Currently it ignores any *_proxy variables, and consequently validation fails when there's no direct internet access. Research I've done so far suggests that the limitation lies in OpenSSL, not stunnel, hence this email.
