I've got a problem with the authentication features of Servlet 3.0:

With this code in a Servlet v3:

log.info(""+request.getUserPrincipal());
log.info(""+request.getAuthType());
log.info("===^===");
request.logout() ;
log.info(""+request.getUserPrincipal());
log.info(""+request.getAuthType());
request.authenticate(response) ;
log.info("===v===");
log.info(""+request.getUserPrincipal());
log.info(""+request.getAuthType());

I would always expect to see the Username/login windows, because of the logout() function. Instead, it seems to be a 'cache' mechanism which repopulate the credential and cancel my logout ...

Is it a problem with my firefox, or something I'm missing in the Servlet code?
