Subject RE: SSLSession invalidate
Date Tue, 06 Sep 2011 22:29:22 GMT
Don't assume your SSL session or connection hasn't been invalidated just because you aren't
asked to choose a certificate from your browser certs when you log in again.  In our system
(Tomcat 5.5.33), I know that our HTTP session and Single Sign-on session are invalidated upon
logout, and we see similar behavior (no need to select certificate) upon re-login because
the browser caches the user's certificate choice (and smart card PIN).  Is your session ID
the same when you go back in?  

If you are using IE and you want to clear the browser cache to select another certificate,
go to Tools->Internet Options, select Content tab, and click Clear SSL state.

thanks mark,

if i understand you correct, it is simply NOT possible to invalidate the SSLSession of which
i can get the id with request.getAttribute("javax.servlet.request.ssl_session")
(it works with this key in 6.0.32)

That is a Tomcat bug it should be javax.servlet.request.ssl_session_id

with tomcat6 as well.

Your wild guess is wrong. That feature is in Tomcat 7 onwards.
