Detect security settings of browsers

Does any web browser (IE, Netscape, Firefox, �) send the browser security configuration, such as �check server certificate revocation list (CRL)�, to the HTTP server when submitting a HTTP request? If yes, what mean is used to send the info (e.g., HTTP header�)? I�m trying to find a way to detect the security settings of user browsers on server side.

No, those aren't sent to the server that's being accessed. The browser does all that (e.g. checking the certificate revocation lists) separate from any user-generated traffic - the web app doesn't get to influence (or even know about) it.
