Ok. I am reading the description for ssl_stapling again, and am
wanting to clarify a few things.

if "ssl_stapling on":
if the certificate of the server certificate issuer is present in
<ssl_certificate>, we do not need to have <ssl_trusted_certificate>
otherwise <ssl_trusted_certificate> must have the certificate of the
server certificate issuer

if "ssl_stapling_verify on":
if <ssl_certificate> has the full chain, we *still* need
<ssl_trusted_certificate>

Is my understanding correct?

thanks,
