Hi,
According to the documentation (http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_ssl_verify) the directive "proxy_ssl_verify" is used to enable or disabled the verification of the proxied HTTPS server certificate. But it doesn't talk about what all different types of validations (like Host Name Verification, Certificate Expiry etc) it does.
Could someone list out the validations Nginx performs on the obtained server certificate from the upstream server when the above said directive is set to "on"?
