For protocols where a separate server certificate may be associated
with each transaction, e.g. HTTP over TLS, you can get the certificate using
RHTTPTransaction::ServerCert()
. This is not intended for
use by a WSP client and will not return useful data. For a WTLS server
certificate, RHTTPSession::ServerCert()
is used to obtain
a copy of the WAP Proxy's server certificate after a secure WTLS handshake has
completed.
