Hi, our app currently relies on using the attribute emptysessionpath=true on the ajp connector due to having most of our 
urls not containing the context path of our web app. 

We are having trouble with the jvmroute switching as the Tomcat code doesn't appear to 
check if the jvmroute is valid for that node? I noticed in the 
org.apache.catalina.session.ManagerBase there is some code that is 
commented out, which would fix the route replacement.


Is it possible to uncomment the route replacement check below in ManagerBase?


code from ManagerBase:

if (sessionId == null) {
            sessionId = generateSessionId();
        // FIXME WHy we need no duplication check?
        /*        
             synchronized (sessions) {
                while (sessions.get(sessionId) != null) { // Guarantee
                    // uniqueness
                    duplicates++;
                    sessionId = generateSessionId();
                }
            }
        */
           
            // FIXME: Code to be used in case route replacement is needed
            /*
        } else {
            String jvmRoute = getJvmRoute();
            if (getJvmRoute() != null) {
                String requestJvmRoute = null;
                int index = sessionId.indexOf(".");
                if (index > 0) {
                    requestJvmRoute = sessionId
                            .substring(index + 1, sessionId.length());
                }
                if (requestJvmRoute != null && 
!requestJvmRoute.equals(jvmRoute)) {
                    sessionId = sessionId.substring(0, index) + "." + 
jvmRoute;
                }
            }
            */
        }
