Holger,
I've verified that URL rewriting of session ids works as expected with
GlassFish.
Note that GlassFish v3 implements the Servlet 3.0 spec, which adds standard
configuration support for session tracking modes, both declaratively in
the deployment
descriptor and programmatically (e.g., via a ServletContextListener).
For example, you could implement a ServletContextListener that disables
cookies
and enables URL rewriting of session ids, like this:
public class MyListener implements ServletContextListener {
public void contextInitialized(ServletContextEvent sce) {
sce.getServletContext().setSessionTrackingModes(EnumSet.of(SessionTrackingMode.URL));
}
public void contextDestroyed(ServletContextEvent sce) {
// Do nothing
}
}
