Asp Object: ClientCertificate

ClientCertificate
The ClientCertificate set obtains the verification field from the Web browser publishing request (specified by the X.509 standard ).
If the Web browser uses the SSL3.0/PCT1 protocol (that is, it uses a URL starting with https: // instead of http: //) to connect to the server and request verification, the browser sends the verification field.
If verification is not sent, the ClientCertificate set returns EMPTY.
You must configure the Web server to require client verification before using the ClientCertificate set.
