I understand what you are saying, Javier, if you have a round-trip situation, where you set cookies in one response, and then test for them in a follow-up request.
But I'm not convinced that's how Tomcat does it. The first time a client connects to a server, there will not be any cookies, session or otherwise, for the client browser to send to the server - but Tomcat can still figure out whether or not cookies are enabled in the client browser. At least, that seems to be the case with my application: Tomcat automatically decides whether or not to apply URL rewriting if I call the HttpServletResponse.encodeURL() method. I wonder if anyone here knows for sure?
