Http server instead of own server?

Teddy, thanks for clarification.

But in the meantime, how secure is TLS authentication of remote mandos
client-server authentication against the exploits discovered recently
like the one at http://www.isg.rhul.ac.uk/tls/, and the /. discussion
at http://it.slashdot.org/story/13/02/06/2337228/researchers-devise-new-attack-techniques-against-ssl
and at http://tech.slashdot.org/story/11/09/20/1833232/hackers-break-browser-ssltls-encryption?

Just eager to know how mandos server-client architecture prevents such
vulnerabilities?! Thanks again.
