I am interested in authenticating users via their X.509 certificates. Lightstreamer's username/password authentication mechanism is not sufficient. Normally, I would perform X.509 authentication within a servlet container by retrieving the "javax.servlet.request.X509Certificate" attribute from the HttpRequest; however, to my knowledge Lightstreamer does not provide access to the HttpRequest or any other means to access a user's certificate. Can you provide any further guidance, short of relying on an external web server's preexisting authentication mechanism, which would provide access to a user's X.509 certificate via the Lightstreamer server?

Thanks in advance for your assistance.
