HttpClientCertificate Class
Provides the client certificate fields issued by the client in response to the server's request for the client's identity.
Assembly: System.Web (in System.Web.dll)
If a Web browser uses the SSL3.0/PCT1 protocol (the URL begins with https:// instead of http://) to connect to a server and the server requires client certificates, the browser sends the client certificate fields contained in its digital certificate.
For more information about digital certificates, see the document X.509: Public-key and attribute certificate frameworks, available on the International Telecommunication Union (ITU) site at http://www.itu.int.
